Do you think you need to roll over in a simulator of a semi-truck to understand the unpredictability, and likely deadly outcome of that, and do everything to prevent it?
How about 4 wheeling, it never occurred to me to roll over my Jeep, to train that rolling over was very bad. or falling off a mountain, or driving into a really deep ditch ... Some things just fall into the realm of common sense. So we never rolled over or crashed my Jeep in years of what most would consider, yes my wife is in that category, very dangerous four wheeling.
I suspect a simple rollover simulator could handle lots of differing military vehicles. Like they do with helicopters over water. Real training would likely do more than computer simulators and simulator experience.
Simple things like vehicles don’t really need simulators. Just an expensive toys, IMHO.
Just my two sense.
