It's like a real-life Starcraft perk for mechanics repairing armored vehicles: Marine mechanics assisted by augmented-reality goggles with a heads-up display repaired light armored vehicles up to 46 percent faster.
The HUD replaces technical manuals on a bulky laptop with floating instructions, labels and oh yes, 3D models of tools right in front of the mechanic. The wrist-mounted interface is run off an Android-powered G1 (which looks much cooler as gauntlet). Apparently Android's seeing a lot of use as a tool of war. You can check out a video of it here.
