LOL at the folk getting angry, its a beta with NO flippin manual! You make a thread moaning that no one gives ammo yet fail to say how the hell you actually give ammo!
I've put in quite a few hours, browse the forums, looked through the game files for a manual... nada, nothing, no guidance. I had no idea how to give ammo until about 1/2 through this thread when people are complaining about going into cover rather than giving ammo! And even now i still don't understand how it works... What classes have ammo? How do you give it; drop a bag? hold a button? jump up and down? perform squat thrusts?
If you want to see something improve i suggest you actually help people rather than just moaning.
