Marines largely use the the M4 which has a lower recoil compared to the AK. They also have optics for their auto riflemen which is incredibly strong. Majority of their M4s are burst fire, which can be iffy though.

They make use of aquatic vehicles, like boats or AAVPs to estabish FOBs. Only the logisitcs AAVP can place a radio though, despite both having construction. Coyote and LAV-25 allows for exposed loaders + cmd, for more awareness.

Their ability to create FOBs, and use boats with little to cost is strong. Their kits are quite OP, espically their auto rifleman.

The coyote does not bridge the gap for an APC, like the BTR does. Rotating multiple squads can be hard . The AAVP is horrible to drive and use.
