The XV84 commander has a networked markerlight that triggers every time a weapon hits, automatically. It makes no mention of line of sight at all, or mention of wounds. Simply if you hit the target with a gun, apply an ML token. If the commander were equipped with AFB grenade launchers, he can fire up to 18" non-LOS with at least one hit almost guaranteed.

Thoughts? Not the most powerful or efficient but it's certainly a left field tactic that could throw an opponent with the earth caste's invention of bendy light... (Though my thinking is more like a tracking beacon sent up with the projectile more than an actual laser)
