I think Jagdtiger would be pretty OP with Special Operation's flares ability.
Panzerfusiliers at least need to be at the front to launch their flare. And Breakthrough (G43s) is pretty munitions heavy so flares aren't abundantly available in the first place. Spec Ops usually floats in munitions if things go well so arty flares could be dropped all the time to spot for JT.
