If the idea of stand-off armor is to pre-detonate the HEAT warhead outside of its optimal detonation distance, what easily-available/manufacturable substance would make the thermal jet even less effective? Firebricks? (yeah, I know, really heavy). Compressed layers of aluminum foil wrapping fragments of tempered glass (pyrex dishes)? Filled water containers/heavy plastic bags or plastic water bottles nestled between the detonation plate and the hull or turret armor? Enamelled metal plates (it was tried in WW1 for body armor)?

Yes, I know some of these are being pulled out of left field, but if you are an occupant of that vehicle, you may be stretching your brain as to how to survive some overeager marauder or Pact greenie with an RPG or antitank grenade, especially if you've seen some buddies get fragged in their tank or APC.
