Hellfire targets :)
Only if the APS isn’t turned on or is out of ammo. APS is hellishly effective against missiles like Hellfires.
If you are unfamiliar with the state of the art in vehicle APS, this is a promo video of a live fire demo featuring live RPGs and TOW missiles shot at a Bradley retrofitted with the ***export*** version of the Israeli Trophy APS.

Keep in mind that this is the retrofitted, unoptimized, dumbed down for export version that the Israelis are willing to sell us. A vehicle built to integrate this would be even better protected - and even this export system includes protection against top down attack.
