In my time in K-troop, we had both. We used the old 151 jeeps with hard-tops, and also the Hummers.
I remember when we were learning about the Hummers, Sgt Dean (motor Sgt-Cool guy) took us out to the LTA to learn how to drive the Hummers. We found a "little" mudpuddle, and of course, we sunk the thing in it up to the mirrors! That was a nasty surprise. We didnt think that little mudpuddle was that deep. But overall, I found the Hummer to be an excellent vehicle. It worked best with chains in the mountains in winter-time. But it was still good.
The old 151s were really showing thier age by the late 1980s, but they were sturdy little things. I found that we could drive between trees in the 151 where the Hummer would have gotten wedged in tight. The 151s always ground the gears going from 2nd to third, and they used a lot of grease. They would roll over easily, as some of our guys found out, but you didnt have to worry about welding the glow plugs by not waiting for the little light.
So, what do you guys think? Which was better for patroling the grenze? Was it the 151...or the Hummer?
