We can assume it's possible to have an open mind about these issues I'll submit the company and their efforts that quietly has been building towards the Program that draws the most fire. Look at he Funding and it's history, look at the problems that they are solving. The latest that the Army floated was the one where the user said "These would get us killed" because Light Leakage from the Headset, SA Photonics engages, problem solved. The criticism that the OLED Headset is meant for "Only Training" doesn't apply because from the beginning the Army's Goal was the ability use the same Headset for Training and Mission Rehearsal "Bloodless Battles" as you would take into Combat. The twin mission are being fleshed out now by PEO STRI on the "Training" side and PEO Soldier on the "Ruggedized for Combat" by the Soldier Lethality Team at Fort Belvoir. The goal is that these merge in time and we see that is happening now.

 It's not a small thing that these devices from the beginning have used eMagin displays because only those are able to accomplish the Mission of reducing the Size, Weight and Power of the Wearable. The overall goal has been to reduce the load of the warfighter (hate that term) both physically and cognitively. Don't bother if you are convinced that something exists without evidence.
