Think how easy it is for the original country jut to have troops waiting to capture it back instantly.
This is what everyone is asking for.
If folks wish to horde a base, that is fine. All the defenders want is a reason to keep said hordlings around for a while so that they can engage them.
Imagine this if you will: The troops have landed and have taken the map room.
Grunt: "We've captured the map room, but the situation is still tentative. We're working hard to get the AA operational again, but spotters have located enemy troop movement to the north and a Tiger in the bomber hangar."
Pilot: "Uhhhh copy that crazylegs. Be advised, uhhhhh we're strafing the troops to the north, uhhhhh and we'll see what we can do about that uhhhhh tank in the fighter hangar."
Grunt: "BOMBER HANGAR! The Tiger is in the bomber hangar!
Pilot: "Uhhhh yeah, the tank is in the bomber hangar. He just uhhhhh vulched five of our guys on the runway. Uhhhh wait one."
<28 seconds of silence>
Pilot: "Uhhhh yeah crazylegs it's gonna be at least 8 more minutes before we can get a plane with a bomb up here. Uhhhhh erm you see, we expended all ords on the ords bunkers. So ummm wait one."
Grunt: "Oh for crying out loud, we'll have the ack up in 10 minutes."
Pilot: "Ummm crazylegs, you guys are gonna have to hold fast and try to uhhhh get that ack up. Some creeps just showed up and are currently whipping the uhh snot out of us."
Grunt: "WTF?"
Pilot: "What's that honey? Tacos for breakfast? Ummm I gotta bail crazy. Watch out for that tank in the VH."
Grunt: Dammit, get the ack up before those M3's get here!
