Same here happens,although very rarely,when some arty unit loses contact and can't fire.
But that's when i spread them out too far to reduce CB fire damage.
It's a matter of formation cohesiveness,same as other combat units.

But in regards of FO's,they can push out too far on large maps to get better vis,and you mentioned your purpose of delivering accurate hellfire on your opponent(:
Good to keep a mech CO within contact but always safe.
