On SFMA2016 map
The flak bases near HQ and City:
1. The 88 man guns are not enabled.
2. Vehicles are not enabled.
3. Storches not enabled.
Maybe this was intentional or an oversight, I don't know. I went to use an 88 there to shoot at an enemy bomber, but couldn't. I also wanted to run repair supplies to the city with an M3.
