This may not be a bug, but I think it should be. In my opinion, either a specialist is involved in combat, or he isn't... he can't be both.

In the video, It shows 100 drillers attacking an outpost with 39 shields (thanks to a security chief) and while the attacker wins, the security chief still escapes.
In my opinion, one of the two outcomes should have occurred
1) The security chief participated in battle, the 39 shields should have destroyed 39 drillers, and the security chief is captured, or
2) The security chief did not participate in the battle, the shields would have reduced to 30, therefore killing 30 drillers, and the security chief escapes.
