To capture a base, 10 friendly troops have to go into the enemy maproom. However, certain prerequisites have to be met
before those troops are going in:
Airfield:
The maproom is located not on the field, but in the nearby town. 75% of the buildings have to be destroyed (indicated by flag turning white) and ALL anti aircraft guns in town. On very few maps the town is very close to the airfield, in this case some of the AA guns on the field have to be destroyed too, else they might shoot & kill your troops in the town.
Downtime for buildings and AA guns is 45 minutes. There is no way to confirm town status from the map, you have to do visual recon on town.
Vehicle Field and Port:
These bases do not have towns, the maproom is located on the base itself. The automatic AA guns on the base have to be destroyed before bringing troops in. Technically, it's not required to eliminate manned AA and AT guns, but highly recommended. (downtime for manned guns: 15 minutes). Killing vehicle hangars is a good idea too.
Additional notes:
- Very rarely a base has a shore battery that can target the maproom too. Check it before watching your LVT, M3 or C47 die to a surprise 8" shell.
- Friendly troops do not "reset" a maproom
- Troops are acting like "ordnance" for game purposes: If you are getting killed after dropping them, they will continue to run to the maproom. If you reup while they are still running, they will simply vanish.
