fuck yeah finished assignment

Nar, honour guard for the funeral of an ex-cadet, where you are at present arms (with the old SRL rifle, none of this Austeyr shit) for 15-20 mins in 43 degree heat is torture.

Kidding. That's a fucking honour.



Dawn service is torture lol.. especially when some old guy is giving the address and he's droning on and on (yeah, the one at Castle Hill RSL last year was like 40 mins)

I had to do dawn service without a weapon, but still had to hold our hands as if on the butt of a weapon. So your legs are sore, your feet are sore, your neck is sore and your arm is sore.

Lmao.. that's rather stupid..
