HA i know the Answer
MORE SLOTS oh wait theres only 10 
Think more flame troopers would be to much. Mortar man option in an scout team could be sufficient and realistic
Wait i know the answer NO!
no need the balance the mortar squad right now, it needs a total rework first.
How so!?
it has no real purpose, used to be OP, but now its just a gimmick which doesnt do much.
still wondering why there are mortar squads as well as arty radio squads. Could have been just one squad right?
