SCAR-H. Still the heavy hitter we love from MW2 with the SCAR-L upgrades from MW3.
Blackbird/Orbital V-Sat. Still capable of making the other team s*** their pants in fear.
Throwing Knife/Tomahawk/Combat Axe, although it's not as easy to get kills with as it was in MW2 for me

AK-47(or extremely similar) being arguably top-tier and final unlock AR. LMGs being powerhouses. There always being at least one great shotgun. Snipers being viable viable weapons. Claymores being good defensive weapons. A throwing knife or hatchet weapon. A pred missile variant. --- I' gonna startin' about fit'na start fin'tn about.
