Maybe give Spec Ops Panzerfusiliers instead? They have the flare ability on them, and though the squad itself needs some balancing work I think it's one that could definitely be in more doctrines.
(Possibly a special variant without Panzershreks to avoid Radio Silence + Shrek spam. TBH I dislike both Panzerfusilier upgrades and would rather the unit be balanced differently outside of upgrades.)
