Let's see, Bradley is at launch site. The launch site also have sams on the buildings. We attacked bradley, chinook came, but got brutally annihilated by the sams. Poor chinook can't even land to deploy the guards.

Can you fix this? Chinook got attacked by their own sams on the launch site.

Sounds like a conflict with another plugin, because by default the chinook is not attacked by launch site sams.
