not sure where these would fall, but possilbe light SAWS, ad here are some I came up with toda at the UN exhibit at our military museum:
BAR (Browning Automatic Rifle) used by peacekeeping forces as a support weapon, fires 30-06 rounds, 20rd box mag.
that could go for specops, and to balance for terror
RPK. similar to AK, 30 rd "banana" magazine, fires 7.62 russian. it is still used, as it is a very reliable weapon, just like the AK-47.
now to balance:
BAR has fast and slow auto, fast being PDQ (I'd give it a fairl high modifyer, around 8-900 RPMS) and slow around 60 RPMs if possible
RPK could be set at lust over AK rate of fire, and slightly less powerful than the browning (makes up by larger mag size, and ossibly more mobility)
not sure if single exists on it, I'll upddate this with some research later on.
now, you may be saying "but the BA is a WW2 weapon, why put it in" because the UN currently s using it in some missions. suprised me too! it should be easy to get anims for, as there may be an open-source mod or two that has anims for it, and if not, meh.
if you don't like the idea, okay. I'm just tossing it out.
Ok, first, RPK can fire in single fire mode. To the guy that doesn't know of it, http://www.world.guns.ru/machine/mg16-e.htm
it is basically a fanvy AK47.
And I would much rather prefer an M248 over a BAR, the BAR is only used in small forces with no money, military and SWAT teams use the M249 SAW.
But what I would really love to see is this, http://www.world.guns.ru/machine/mg18-e.htm
The H&K 21 and 23. Most of the Spec Ops teams use Colt and H&K weapons, so it would fit right in. Or we could add a complete new class, the support class, it could go, M249, M60, then the H&K 23, and for the shotty noobs, give a Jackhammer. They could have the two Frags, 1 flash bang, and 2 smoke grenades. Eh eh? Yeah, you like it, you know you do.
