Nobody else has reported this but a new defect found in IVAS. We know the Hololens can only be used indoors and is useless outside in the rain, useable only in a Temperature Environment but the potential for Batteries to be damaged in Combat? It goes without saying pretty much everything can be damaged in Combat...probably mean catch fire or enclosed in a non-ruggedized housing...

The US Army has significantly delayed its much publicised US$22 billion contract with Microsoft for an ‘integrated visual augmentation system’. The project involves the development of augmented-reality headsets to provide soldiers on the battlefield with ‘waypoints and other navigation symbology’ similar to those used by combat pilots. While the army says it ‘remains committed’ to the project, early versions didn’t function in the rain and the potential for batteries to be damaged in combat raised safety concerns.
