This is our opportunity to bring soldiers into the 21st century.
Soldiers are becoming better and better as processing more and more information quickly. I know this is a bad example, but bear with me. Have you ever played "Call of Duty" or "Battlefield"? Most people have, and if they haven't they have seen the game in action. Consider for a moment that amount of data that is being presented to each individual soldier on screen at any moment.
1. Your positon
2. Friendly positions
3. Sometimes enemy positions
4. Overhead topographic maps
5. Ammo Count
This is also coupled with voice communications. These players are bombarded with information, and they use it readily. The share locations with eachother, they beomce a collective fighting force the more they play together. This is what should be displayed on glass for all frontline fighters. I know that the iphone was being considered as a forearm attachment with the modern warrior program, and while a start in the right direction, it takes your eyes, and your focus off of what is going on in front of you.
By creating a HUD designed by and for fighters, we can really capitalize on the use of glass. If this were coupled with other COTS products, which can provide GPS location, text messaging, email, and "smart reports" (such as in FBCB2 ie IED, MEDEVAC, INS, etc.) the military as whole could become more interconnected and information would be shared at the speed of data.
The technology is out there. If the President can have a secured Blackberry, soldiers on the battlefield can have simliar technology.
