A SPARTAN-III overlooking a Covenant glassing attack (of sorts) and preparing to return to the fight, whilst holding onto one of his comrade's dog tags.
This is one that I've done a while ago now, but never got round to releasing it.
but it'd be funny. i can imagine this now. two combine soldiers are exiting the mess hall of their base, and a grunt, on an ignited propane tank, flies past them squealing bloody murder. the two soldiers look at each other, before one hands the other five bucks.
indeed, i would've recorded that and posted it on youtube though, if i were them. something like that's bound to get a million views in two days at least. would've made them famous, if they weren't evil.
