Pretty sure maneuvers are resolved separately. Which means you can do things like ram twice, repair twice on a station, shoot in the middle of movement with Demolisher... ...and things like being forced to run over mines in your path. You win some, you lose some. Ideally, Engine Techs should have gotten you out of position to hit the mine in the first place.

Chirneau is an officer, not a commander. You're going to need to free up some points to take... probably Motti. Soontir really needs escorts to run with him. Even though he has a Scatter token, he still only has three hull. A quick focusing down and he dies almost as quickly as a regular interceptor
