I modified the Forest 1 scene to have team1's LZ above my base and team2's further away. It works for the most part (As evidenced by a pile of dead enemy rockets, thank you SAM sites) but on occasion a drop pod will come right down on top of the base. I'm using the "Imperal Army Assault" activity (
