Did we get any answer on this one?
After reading I came to the conclusion that: After unleash hell is used (as command or from handgunner ability) you can not use it as in
"To use a command ability, you must spend 1 command point, pick 1 friendly model to issue the command, and pick 1 friendly unit to receive the command."
But another handgunner unit can recieve it from the within 3" abillity.
So for example you can unleash hell with unit A using a command point and then handgunner unit B (if within 3")..... Have i gon crazy or should this work???
Btw Ironjawz player here so Im not that biased 😁
