Opening a ration pack for lunch

Returning from a long day on the 8x8 on some private property - I decided I needed a feed before loading the 8x8 up on the trailer and heading home.
I had a ration pack on board that needed eating, so I broke out the FRH and a few other bits of kit I rarely use.

Nice hiss?

Fortunately, nothing old enough to hiss in this.
