Base Backdoor: Cheap Point of Entry?

[Majik]

Now if you wanted the backdoor to really get interesting, you remove the ability for either force to open it from the outside. That way you have to either 1) Get a cloaker or someone else into the base to come and open the door, or 2) Wait for a defender to come out and then rush it. An ams driver could deploy at the backdoor, a cloaker walks up and opens the backdoor from the inside, and the ams driver stands there to keep the door from closing. He dies and the troops stop flowing long enough for the doors to close, and you have to wait for someone on the inside to open it again. FLAME ON
