I was thinking about some new battles like:

Ambush( ambush name will then need to be changed): One team of mercenaries defends a convoy while the other team needs to destroy it. There will be CRU's with the convoy so the defenders can spawn in it, and some large turrets to help. The attackers will have spawners trough all of the convoy's travel way. The defenders win when the convoy( or what's left from it) reaches the Fort/Base/HQ. The attackers win when all of the convoy or the defenders clones are all used ( even if it reaches 0 the defenders can't spawn but the ones on battle can still fight);

Siege: Defenders need to defend NULL cannons to destroy the MCC before it reaches the docking area to bring in reinforcements. The attackers needs to destroy the NULL canons by planting 3 heavy explosives but they can be deactivated.

Capture the Intel/HVT/Launching codes: Defenders need to defend the objective until the attackers are out of clones. The attackers needs to capture the objective and bring it to their MCC or extraction zone.

King Of The Hill: King Of The Hill.

Convoy, I always like these style gameplays. a lot of direction, which a lot of blueberries will benefit from.

Capture the (flag) intel. Everyone should understand this, and should fit in just fine.
