Here is my spin on it:
What I envision is similar to the Battlefield series. Infantry spawn points could be deployed by carrier vehicles (goon, m3, lvt, etc.). The spawn point will be a physical representation of the active cv that remains stationary and operable until it is destroyed by the enemy.
Attacking players could choose a faction (American, German, etc.) a weapons kit (rifleman, heavy weapons, etc.) and then spawn out. Just like it is now, the town should be white flagged and all auto-ack down before the troops can attempt to capture it. To capture the flag, a soldier would have to interact with it for a certain length of time (as if he/she was changing the flag).
Defending soldiers could would have a spawn point near the town (as long as the Barracks were up). If they are down, then no troops can spawn from that base. Stationary and support weapons could be operated to defend the map room.
The way I see it, it would be a small-scale FPS that combines the use of mechanized vehicles we currently have on a grand scale.
