Weapon Scavenger to help find alternatives to the M1A.
Marked for Death is mandatory for me unless there's a better marker on the team. Surplus Pouches is best final card for any build.
Cocky is to swap from sniper firing to be able to sprint sooner. I'm not even sure Cocky helps you sprint sooner on swap.
Drop Cocky and damage for Guns Out, Energy Drink. Steady Aim, Tunnel Vision, Reload Drills. Might be best to try swapping out all alternatives to try both extremes: damage vs. ADS etc..
