I'll add one more: so much of what platoon leaders do now is teach about technology. There's only so many hours in the day for training, and (even back in 2013!) the load was starting to cause deficiency in basic combat tasks. We just didn't have the time between all the requirements to get everyone proficient in the myriad of sensor tech we ended up carrying. Plus, if it's possible to break something believe me a Private will figure out how to do it.

This right here is a question I hope they're thinking about. In an actual fight, you may need to pick up gear off the ground. What happens if you can't, because "authentication"?
