A tad warm and susceptible to losing your arms, but if you wait for opportunities you can punch way above your weight. More an ambush predator than a skirmisher. Stick with your team otherwise they'll drill your arms off and try to under-run you. You can pull some big players off the field though if you ambush carefully. You can drop a ton of HMG ammo for extra ATM ammo or another heat sink. Tried it both ways and don't really have a favorite yet. Probably gonna keep the extra HMG ammo since they are pretty hungry.
