Althea, speaking to her beloved MRAP, says, "A 50 ton nuke couldn't take you out." Modern nukes are typically rated in megatons (i.e., millions of tons) of TNT. In contrast, the Little Boy bomb dropped on Hiroshima was 15 kilotons (i.e., 15 thousand tons) of TNT. The lowest yield battlefield nuke in the U.S. armory, the B61 bomb, is 0.3 kilotons or equivalent to 300 tons of TNT.
Al tells Morgan to use the fuel from the helicopter to run the MRAP but there is no method to transfer the fuel from one to the other.
