"Train Like You Fight" Compels the Military to use the same device in the field as in training. Testers found discomfort in switching devices so it will be one HMD, one Soldier, Airman, Marine.

funny, though, Lockheed has one, Rockwell has one, SA Photonics Microsoft has one. Maybe some were prototypes. We'll see but they will be used in ever possible environment so the attributes that keeps eMagin displays, temp extremes, brightness, contrast, SWAP in all current programs means they will be in future programs as well.
