"Dropship Bombs" clearly are the best weapon in the game!!
Did this a few times on each map just to confirm:
What: Use Dropships as Bombs, Enemy Tank Barricades, Smoke Screens, Tank Traps, etc.
How: At game start, the enemy on defense always has anti-air well in place guarding the outpost.
So simply select any vehicle and set your drop point to where you want it to do the above tactics. The shot-down crashing dropship does a great job of defeating any plan the enemy has of defending the base...especially when you drop 272 of them during the course of the game.
I had more than enough vehicles and dropships to completely stop the enemy from forming any kind of defence, mounting an attack, or recovering the base once my team captured.
Probally a good idea to stop this for the next demo/game
