An M60 as in the machine gun?
If so, team 2 die horrifically.
You have someone with perfect vision firing 10 rounds a second, with the bullets travelling at 800+ m/s (SO SAYS THE ALL POWERFUL WIKI)
So if everyone starts at 0.5 km, they have dozens of perfect shots bullets at them from Bullseye alone inthe first 3 seconds, let alone Wesley and Deadshot...
