Hmmm, well, since some battles last 10-15 turns
(minutes!) And that troops got 30-40 ammo...
Image a trooper with 40 ammo clips strapped
to him... you want him to resupply on top of
that?!
Try pacing yourself, don't continually
shoot left, right, center...
Hint : USMC M16A1 could do full auto, M16A2
could fire at most 3 shot bursts...
That's so Vietnam troopers wouldn't continually
run out of ammo as much, as they were wont to
shoot at their own shadows in company strenght:)
The enemy has to pace himself too, don't worry
about it.
There's more to this game than just continually
blasting away. Try sneaking, or positionning
better. Local fire superiority is always nice,
but that doesn't mean firing continuously at
targets that are out of effective range, hmm?
ie : SMG teams firing at 500+ meters...
