- Let's start a sequence of Swedish tanks at the start...the first Swedish tank, and our first Tier 1.
NA forum thread: forum.worldofta...

All my life my dad has told me that thinking is highly dangerous and usually gets you into accidents. Best to leave it to the horses, they have big heads.
It's great to finally see someone share this wisdom.
Minor notes from someone with a skosh of antique vehicle/machine experience...
The conical headed fasteners likely have a square shank that mates with a similar cutout in the plate. Basically an armored carriage bolt. Such fasteners were very common at the time.
The pedal layout (throttle bracketed by clutch and brake) was probably the most commonly encountered, til the current standard you mentioned, established by Cadillac.
For their seeming primitive nature, leather faced cone clutches were amazingly effective, and cone clutches are still found (albeit with modern friction materials) in many applications.
The drive belt for the water-pump and fan could be leather, or canvas, or a rubberized/impregnated canvas/linen material. Such drive belting is still found in service with innumerable older machine tools because of it's sheer durability. One does need to coddle them far more than more modern V belts or flat/cog drive belting though, as they can slip annoyingly if one lets the facing get glazed or some stray oil on the pulleys..
Alemite fittings have gone through a number of variations, it's just the "Zerk" pattern that really survives to present day. The ones found on the suspension of this vehicle were likely the similar, but pre '29 "button head", as the Zerk pattern was not common til post 1930. Also, if one looks at the water-pump, there is the old hand-screw "grease pot" style lube fitting, that remained in service on may vehicles in that application til well into the 1950's.
All in all, that the vehicle did not have a form of constant loss lube system is fairly advanced.
The lighting fuel tank is likely for an acetylene ("prestolite") system. Interestingly bizarre in it's own right.
Thanks for your efforts!
"So we were thinking, and yes I realize that's a dangerous thing to do." That had me laughing so hard! Keep up the great work my friend!
You may get a wild Irish Tanker rampaging through Stockholm in a S-Tank.
🤔🤪👍
Excellent synopsis sir. Well defined, well executed. Very informative without being boring. Thank you entirely for this series sir, I eagerly await the next episode.
"So we were thinking, and yes I realize that's a dangerous thing to do"
You guys are the best. Cheers Chief and all those behind the camera and editing.
TheChieftainWoT If you are still in Sweden you must go the The Swedish War Museum in Stockholm. Seriously the have a couple life size displays that are both spectacular and horrifying. Someone did a amazing job there
Didn't have much time, went to Vasa instead.
Understandable!
Maybe the wooden "firewall" was actually more a heat isolator than fire spreading preventer? So at least tre crew would not be directly exposed to the engine?
Pretty sure the cotter pins are simply snipped off with cutters or even cut off a rotary cutoff tool, and replaced. It is easier than unbending them, and they are cheap and plentiful. It is like saving used nails, not really any point. Of course, that would be on the rare occasions when you had to disassemble the entire track. Usually, you only need to remove a single pin to break track, or two of them if an entire segment needs replacement. In that case, depending on where you are and what tools you have right to hand, it is probably easier to just use pliers and/or s hammer to unbend the cotter pins instead of finding a cutting tool. So I dont see the cotter pins being much of a real inconvenience. I mean, probably a lot of these tracks are never taken apart at all in their service lives, beyond breaking track and random segments. So who is going to have to remove a couple hundred cotter pins? Even if they do, hell thats what maintenance branch is for. It is still better than a muddy hole and wet boots and bullets and shells all night long..
It is a partition or a bulkhead. A firewall is a firewall, fire resistant by definition. it is a special subtype of bulkhead or partition, serving a specific purpose. they are so common on engines now that most people assume that it is a word for the bulkhead behind an engine, but it is not.
Love it that Chieftain is wearing the Swedish Armoured Forces pin in the videos on Swedish vehicles. :)
i only stumbled on the chieftain, by accident ..but I like! bloody good series.
I think that chain and hook may actually be more intended for tearing up barbed wire, though no doubt you could tow a comrade with it in emergency. It looks like a poor shape for a tow hook though, it would fall off easily with any slack.
New Inside the Hatch video...and the crowd goes YAAAAAYYY!!!
It's about Swedish Tanks....YAAAAAAAAYYYY!!!
There will be more coming...YAAAAAAAAAYYY!!!
Hurray for you, Chieftain!
By far the best series on UA-cam for me
This tank was placed on the island of Utö, by the entrance to the area we used to stay nearby to the sharp shooting area. ...around 1976...
i miss the *sweet chieftain transition*
Hey, this new intro is actually really cool! I also liked the old one, but this is just very nice:)
I think you might find the funny conical bolts are made on a similar system to the bolts that hold armour plates onto battleships. The shaft of the bolt under the head is a long cone and the roots of the screw thread are equal to the smallest diameter of the cone. There are two effects from this - one is that the bolt does not break off at the start of the thread when hit, sending the nut and remaining bolt shaft flying around inside to the inconvenience of the crew. The other one is that when the bolt is tightened it locks into the conical hole in the plate and won't rotate - look up 'Morse Taper' - so it would be relatively easy to undo the nut - you would then need to use a punch to hammer the bolt out of its hole - there is usually a conical hole in the end of the bolt for the punch to go in - the more modern US approach would be to stick a couple of ounces of C4 on the threaded end of the bolt and blow it out, like on the torsion bar suspension of an M60.
That new intro is very pleasing.
Wow. No electrics. At all. And hand traverse. .
And it looks like a shoe.
the driver "not having much to monitor" i believe is incorrect in a sense. much like many WW1 aircraft, much of the engine status is kept track of solely by sound (fuel mixture is a good example) i'd assume it'd be much the same for a tank of the era
Yeah, your right. My father always told me a really good driver doesn't need any gauges, he has eyes to see and ears to hear and knows which gear his vehicle's gearbox is in. So he has everything he needs to estimate speed and RPMs . . .
To be fair, I think they have turned the background music down a notch since the older videos. That's a good thing. We're almost there!
I honestly love that intro, thag made my day
It is!
Super Conqueror/Leopard / IS-3/ STA-1/ M103 are all in the intro
STA-2 you mean :P
15:10 What do you mean? The first Swedish tank design, the L-10 had a separate machinegunner in the hull. Later models of Swedish tanks got rid of the hull machinegun completely.
55hp engine! My snowblower has half of that.
Chieftain, we miss watching how someone would actually get into all of the crew positions, you provide a good representation. Could you go back to showing us again?
I don't think this tank really has the substance to do a full two parter.
Cool work Nicholas & WG, and Arsenalen :) ..didn't the Germans capture a few/some Whippets in WW1? I could've sworn over the years of my own general interest in military & engineering histories, that I read somewhere in soft/hard-back format, that due to combat damage, a few Whippets were captured without being destroyed by artillery or their crews.
I wonder if the armour would have been enough for the .50 BMG "anti-tank rifle" cartridge.
(Yes I know that BMG stands for Browning Machine Gun, and that it was never really used in a dedicated anti-tank rifle, but prototypes exist)
Mostly likely not but the chances of it coming up against something like that when the tank was designed would have been pretty low.
not even close, a modern 7.62x51 or 7.62x54R AP round would go through the fm/21 just as easy as those bullets slam through a single layer brick wall.
I'm really digging the new intro.
Another great video. I am looking forward to seeing more.
just noticed the newish intro, it's badass
Yeah, but they kepth the terrible background-music...
Too bad you couldn't make it to Stockholm on the 26th, as that means there's a missing autograph slot on my goodie bag t-shirt next to that of your colleague Richard "The Challenger" Cutland's :)
Love your videos!
Sorry. I posted on FB and a Reddit that I would be at a certain pub in Stockholm when I was there. I guess you missed it.
TheChieftainWoT Well, np, I wouldn't have had time to go into the city anyway, and don't use FB on my phone.
I'll just have to keep an eye out in the future :)
Love the new intro!
(Also, Inside the Hatch on ELC.)
These are so good, and this guy is super cool.
Nice intro guys! Like it.
Fascinating. Thank you!
awesome intro.... same. OLD. BACKGROUND MUSIC!!!!
loving the new animations!
Hard to believe there aren't more wooden firewalls....
Depending on the wood, it could work. you don't need to keep the flames out forever, just long enough to get the crew out. Of course having the gaps on either side wouldn't really help too much.
It's vents, so you can really enjoy the fumes at all times.
Especially since they can turn into Walls of Fire!
PRETTY!
Thinking doesn't that lead to summoning the Good Idea Fairy?
Hush. You are tempting fate
great vid as ever :-D Looking at the inside you see just how many bolt heads there were to break off and rattle around when hit. Ouch!
l prefer the old intro but personal taste......
Not much worry about that. That armor is only for stopping small arms fire. Any artillery - any at all - is going to punch clean through it like paper, so there is little reason to fear the absorbed force of the projectile will break off any bolt heads. Bolt heads break off when shot BOUNCES off the armor. Roughly the same reason a hit on a person wearing a bulletproof vest will often knock them over, but the same doesnt happen with an unprotected person (although hollow point projectiles attempt to create a similar effect).
Yes another one of this
id say this armour is about the minimum requirement to have on a tractor in a Moose infested enviroment.
Also Springtime plowing needs tracked instead of wheels on most occasions.
Best regards.
btw- mildly interesting minor point: According to Wiki the Zerk patent is from 1929.
thats one sexy new intro, I must say
Another awesome vid, thanks.
Speaking of World War 1 era tanks, are you planning on doing an episode on one of those? FT-17 would be the easiest to find, I suppose. British Mark I-VIII tanks, I'm not sure if there are ones that are still fully intact. As for a German A7V, there's only one remaining example in an Australian museum.
Ryan D Tank talks by the guys at Bovington has quite a few of the ww1 tanks
The A7V is currently on show for a few months at the Australian War Memorial in Canberra instead of at the Museum in Brisbane. The AWM also has a Mk.IV Hermaphrodite (it was used for a War Bond drive in Australia with its Australian crew during WW1) and a FT-17 (Gift of the French people after WW1).
awesome vid. Do the Stridsvagn 103
14:08 all of those bolts scare the piss out of me after reading Tigers in the Mudd
TheChieftainWoT Please make a video of the Stridsvagn 103 soon, i got many people calling it as Self propelled AT gun and/or Tank Destroyer now, claiming the turretless design being the trademark of a tank destroyer.
IMO that model t is the coolest vic there.
Or the sugga.
My thought wasn't how much things have changed, but how much so many of the basic concepts have stayed the same...
Great video again, but the new intro is really off, especially that you kept the old theme music of the show, which I'm happy about that at least that remained.
I love the new intro
I doubt they ever carried more than 3 crewmen, there is no point. It is very unusual for you to be facing enemies in multiple directions at the same time, and you would usually be operating with other tanks even if you did end up in that situation, so you could cover all sides. 99% of the time, you will be firing towards the front, and one gunner can easily move to meet a threat appearing in front or behind, especially since he actually has a turret, unlike the Whippet. More men would just get in the way. It is not a breakthrough tank like the Mk I-IV, etc, expected to be wading through a battlefield surrounded by enemies and machine gun nests. 3 crew is ideal: driver, gunner, and commander, who serves any extra guns when needed, and maybe loads and fetches ammo for the gunner. 3 crew also allows for redundancy if one is wounded.
Nice new intro boss.
Hey Chieftain, how often will these videos be released? Every week? Every month?
Happy to see you and WG visiting Arsenalen, that place is great.
A stronger engine is good to have, but you don't necessarily get much more speed unless you change the running gear as well.
I think the gearing is primary. Less power means you have to gear it lower to move at all. Just putting a more powerful engine in wont help if you just hit redline in top gear at the same speed as before. Suspension limits spee more indirectly, as it becomes mostly a matter of how abuse much the crew can stand.
@@justforever96 I guess I understand better now when people dislike me answering their old comments. I don't mind! but I don't really have any clear idea what I was thinking. As you say, there are many factors involved here. I really wish I had been just a little more verbose when I made that comment.
Woo, fancy new intro you got there!
Really hope you'll do the S-Tank
If this tall beanpole will fit into that sardine can . . . ;-)
I just noticed that the Super Conqueror is in your introduction.
Not sure if you knew about this already, but an artist on Pixiv drew some fan art of you driving a Chieftan that is commanded by GuP's Darjeeling. I can link it if you would like.
good job doing this video :)
I desperately believe the old tech tree needs to come back plus a few extra tiers..... be cool to go from ww1 era to almost modern day. I understand they can't do Abrams n such due to chobhams classified status....
yes!
woah...like the new intro!
Cool new intro
The Intro shows the Super Conqueror, not the standart one we got in WoT. Does that mean we get that thing in WoT soon? :D
Crazy Cheese I notice it also, but it only have the extra armor on the turret and gun barrel.
Yeah, it's missing the Armor on the hull. i hopped onto Status Report and WG does infact plan on giving the Caernarvon it's old turret back and giving us the Super Conqueror at some point.
FUAROCK! Keep up the good work.
now im going too watch the same video on your channel
Isak Ahlback You already are.
breadbasketbomb insert facepalm
Epic new intro!
That is in remarkably good condition for its age...
*Edit* The tank I mean, not Chieftain.
*Edit* Well, Chieftain too... ;)
Had you been in America before being filming, your accent seems to have an ever more subtle Americanised accent than usual. :P
Oooh, nice new intro!
Okay, you really need to change the background tack. I'm going insane listening to it.
+TheChieftainWoT Thank you for the videos and Happy Holidays :D
Arsenalen
Arse-nalen

Sorry I couldn't not say...
Dylan Milne You and I think alike...
That's where the swedish stridsvagen enlarger is made?..
does that firewall gap mean that if the tank took a hit in the front, all the fuel would pour into the crew compartment?
what are your favorite tanks to look at up close ?
I have a thing for milk tanks, personally.
What stops someone from shooting at the vision slits and just blinding you
Human Decency?
Why did I saw his head at 10:48 didn't he do it inside it?
WHEN ARE YOU GOING TO SHOW OFF THE CHIEFTAN? I WANT TO KNOW WHY IT'S YOUR FAVORITE!
i fell bad for you can't get too do a video on the bkan gets send to sweden gets the fm/21
Yaaaay new intro and production :D and then old music starts playing -__-
The intro...is that the Super Conqueror?
So it is
Where do i get this 1:1 scale model kit?
I thought you said "the nude Swedish line of tanks is coming out" and now I'm not sure how I feel
"You go around marauding the Enemy's Rear"
uhhh no, I'll pass thanks.
But you feel free to be a Butt Marauder all you like
Chieftain, is there an opportunity for you to do the IS-3?
Is that superconq at the start in the intro a hint?
Sovietskikh Few days ago I saw some Superconqueror renders, you can find them on Status report.
Ando Bando I know but this is the first time we've seen it in official WG media. The tank itself has been known about for more than a year now.
It looks like a metal shoe on tracks
The correct name of tank is Strv m/21 not Strv cm/21.
fm/21 står för Stridsvagn,försöksmodell 1921
Vagnens korrekta benämning är m/21, inte fm/21. Dock benämnendes fm/22 inledningsvis, men detta korrigerades ganska snabbt till m/21 efter påpekan från Burén.
Gunnar Österlund ok, då har jag missförstått det. Den felaktiga benämningen står dock på informationsskylten vid vagnen i fråga.
Om det står så på skylten skall jag se till att det rättas till.
Why do the bolts in some tanks have pointy heads?
I'd guess to reduce the shot trap
So that if a bullet or piece of shrapnel hits them, the pointy-ness is more likely to bounce the impacting object than a normal flat bolt-head/nut, which most would likely crack, shear or break off without the angling and the extra material of the point.
+10 points to Impact Damage.
Razor1uk ah that does make sense.
Catrik because swag
porque no ponen subtítulos en español?
taco
hello Chieftain. how r ya today?
ohh that intro whew😍😍
check out theorangedoom....
nice new intro ,same shitty and repetitive music in the background
btw i missed your videos Chieftain, glad you're going to do more episodes
ITS A CLOWN CAR!
Is anyone else getting sick of the same track playing over and over again in a loop in all of these videos?
jeemiaas yep, and I'd unsubscribe if I wasn't so curious about the interior of tanks.
jeemiaas no
To be fair, since the older videos, I think they have turned the music down a notch when the Chieftain is speaking. The older ones were properly unwatchable because of the musical loop.
Da na na na na. Doo doo doo doo doo.
Not really
It looks like a shoe with tracks
