It’ll be second-best training. But it’ll be a lot cheaper.
OTOH, the Scout-Sniper has to be good at observation and field-craft too. You only get a shot further on down the line.
If they can make the parts amenable to simulator training excellent, then they can focus on fewer goals during real-world training. The result (if done right) is first-class training for the price that would produce lesser training if it was all done in the real world. If one of my kids is going into combat, and whatever the training budget, I want the right parts of it done in simulators to get the most bang for the bucks available.
