Something could be bundled at Tank hunter to make place for Vehicle detection. Cons ability could be removed since it is obviously better to have the ability as a global one instead of beeing bound to an unit. Looking at loadout picking rates (200+ and Top200 across all game modes) Tank hunter still could get a buff after all.
It already has been buffed, it got ML-20 replaced by B4 and PTRS a CP earlier.
The problem with commander has little to VC and imo there are other abilities that should be looked at (PTRB/camo).
I personally would rather see "mark target" in TH thanks VD.
