The only US Army tactical vehicle I actually enjoyed driving personally was the now-obsolete jeep, in the M151 series. Replaced by the humvee, which I never liked.
The 151s were compact, light, close to the ground, almost like toys to quickly scoot around in, despite only having a modest-horsepower 4-cylinder engine. You could strip the doors and canvas roof off them, which I did whenever I could, and flip the windshield down over the hood.
Good ride with 4-wheel independent suspension, and the later -A2s had a 4-joint rear axle design that resisted flipping. Hell, the A2s even had electric windshield wipers, a big improvement over the former manifold vacuum operated ones. If you were lucky you could even get one with a heater. LOL!
I loved the M151, I'd get one today if I could, and be allowed to legally operate it on the street. Of course a death trap, as tactical vehicles were, and many no doubt still are. No seat belts, no air bags, no crush resistance, no ABS, no nothing.
Yet I used to fly down pot-holed dirt trails at frightening speeds, the only thing holding me inside being a death-grip on the steering wheel. Ah, to be young again and foolish, and given such wonderful toys to play with.
