I put Humvee
a military vehicle that combines the features of a jeep with those of a light truck.
[Origin: 1985�1990; from the pronunciation of the initials HMMWV for H(igh)�M(obility) M(ultipurpose) W(heeled) V(ehicle)]
Yesterday there was a discussion about this and it was felt that HUMMER, which used to be a military term is now confined to a civilian SUV that was based on the original military vehicle.
What is in the clue is the military vehicle and HUMVEE fits that description and modern usage.
