Balanced Early-Rank Loadout For Mobile Offensive

If you don't like lugging around a LMG, try M4A1 instead. They are maneuverable early-rank weapons that can be modified to be effective at most ranges and situations, letting you be more aggressive and mobile.

Consider Extended Mags Attachments

Due to the new Body Armor mechanics and having to fight whole teams, having a larger magazine size is highly beneficial. M4A1 comes with 50 or 60 round magazine attachments.

All Attachments List

Track Down Supply Boxes For Killstreaks

As you'll be on the move a lot, you can hunt down a lot of Supply Boxes scattered across the map. The Kill Chain perk lets you grab more killstreaks for use against hard targets to get ahead.

All Killstreaks List

Choose Renetti For Easier Control

renetti

If you have a hard time controlling the big recoils of .357 & .50 GS, pick Renetti as your sidearm instead. It has very good handing and decent range for a handgun to be effective as a backup weapon. Renetti was introduced in season 3.
