I recall a rule that did not let a minelayer deploy a mine during the deployment phase when it could trigger in range of a model. I see the rule in the wiki has the restriction for other camo markers, but not enemy models. Was that removed in N3. Or am I hallucinating.
Nope your good for deploying with troopers in the trigger area, just not Camo Markers. Same with Koalas. Also note this only applies to things with a Trigger area. So you can deploy a Sensor within 8" of a Camo Marker.
