Nope, but you don't really need ammo if you're clever about it.
Protip for survival: when there's only one enemy left (it'll tell you to "take out the remaining enemy"), run around picking up the guns of every dead body plus the naturally spawning guns. You'll get plenty of advanced rifle, combat MG, mini gun, heavy sniper and RPG ammo this way. It's pretty safe as there's only one enemy left and they are usually in an obscure spot where they can't see you. If your team mates have died and you're the last left, then prolly not worth the risk of losing the survival over some ammo, in which case just kill him and try to gather as much as you can before the next wave begins.
I'm a master of parachuting now lol. It gives a bit of experience points but no money unless you're betting. Speaking of, our crew stats really suck. People making shit bets and losing etc. Get your shit together SKAU!
