Well, yes, many more things to do. You can drive your HMMWV through a ford, and have a rock fly up into the engine compartment and knock off all the blades of the fan, which are theoretically a flexible plastic.
There's more to do in South Korea's heavily forested Rocket Valley, just a few miles from the demilitarized zone separating the two Koreas, than fire rockets. In quieter times, people tend vegetable patches along ice-cold streams.
But on Wednesday, a U.S. artillery brigade based in the South heated things up, launching a barrage of rockets close to the border town of Cheorwon.
Or, north of there, during the same exercise, you can be driving down the road that runs along the ridgeline paralleling the DMZ and have a small piece of metal come up and pierce the hydraulic line for the brakes of same HMMWV, leaving you stranded for the night until they can get a tow vehicle up to you.
Fun times, fun times.
