Just be careful where you deploy it since it has no attacks and cannot move. Enemy may use this to be safe from your shooting.
This. All of this.
So many armies would just say "Thanks for the safe place! Imma just hug this hunk of space junk so you cant shoot me. Don't worry, I'll charge you next turn."
Hell, my astartes jump heroes could just beat at it with their fists while cackling. They aint gonna kill it with combat weapons, and on your turn the hammers and force weapons come out.
