Just this day , I picked up a Sentry Kit on Rush on Attack and was on a surprisingly good kill streak , sadly ran out of ammo and so I went to look for 3 of our supports while running for my dear life . I said it in chat , that I need ammo and I ' m a sentry . Fucking hell , no one dropped ammo and suddenly everyone changed their classes and so there was only 1 support guy in my squad . I keep telling him Bro , I need ammo please , nope , he just went on mortar and got shot by a nearby sniper . This continues as he keeps dying and not dropping an ammo pack . We eventually reached the final objective , no one was pushing so I said fuck it and charged in straight with a club and somehow killed 3 people with melee and armed the bomb . Then my stupid brain finally realized I could just pick up a dead enemy ' s kit , so I picked up an MP 18 from an Assault I killed just earlier and ~~ camped ~~ defended the objective and killed two people . We actually won . Moral of the story No ammo Desperate measures . If no Support drops an ammo , just wait till they die and take their kit to drop ammo for yourself and switch back your kit , or just take the enemy ' s kit .
