I don't think the tech is at the point where it's a useful tool for replacing real life shooting training and drills - manipulations, aiming/shooting, access/withdraw/present exercises and such, BUT, it certainly could be useful for training in the near future with regards to small unit tactics - anyone should be able to see that. In terms of gaming, it just gives a...gaming like representation of using SOME of the items an infantry soldier would use in combat. It's a huge step up from pressing R for knife, c for handgun, and F for rifle. Plus add in the VR experience, it'll be a far more immersive experience in terms of combat. DDgamer is a combat vet/Marine himself, and said the first time bullets cracked by in the game he instinctively flinched and his heart rate shot up - it's more about experience than technically correct motions compared to reality.
You have to reach up to your vest for magazines, insert them, charge your rifle/handgun, draw your handgun from a holster in VR - these are all things that aren't even part of games now, not even ARMA3.
I think we're a few generations away from what Serenity is hoping for, but it IS on the way - JSOC/SOCOM has used VR simulations similar to this for planning ops for well over a decade now, back into the 90s in fact. I'd wager that tech and budgets/cost of real ammunition/ranges will drive the idea that you can do a lot of training by VR in the future. Hell, the US army already has VR stationary ranges for rifles and MGs, I've seen them, and that was ages ago. Dismounted soldier training system was one, and the M4/M249 range was another, I just don't recall the name.

A lot of potential for sure, combining gaming VR ideas and tech with the already existing military stuff, will = new games for civilians, and new ideas/tech for the military as well, as this stuff is driven forward by the market/gamers and military budgets.
Wiley - he did bash his hand against a barrier throwing a grenade - I've done the same drawing arrows and hitting my knuckles on my bookshelves behind me, same with grabbing the shield over the shoulder in Space Pirate Trainer - in smaller spaces it happens, but he COULD turn the camera on, and avoid this entirely, or just draw a more accurate gaming space - since I've made mine more accurate, I haven't hit anything yet, even behind me.
