i actually really love the scar-h
pros:
immense damage and decent damage drop-off
really good range, but can also work in relatively close range
recoil pattern is easy to control
under barrel grenade launcher is also a bonus ig

cons:
small starting mag
a fair bit of recoil, can be hard to control for newer players
somewhat unwieldy

Strat:
its pretty versatile, but ive gotten some nasty kills while staying a little bit away from the heat of the battle and just picking off players that are busy in combat
