The Army says long, repeated overseas deployments often get in the way of continuing education for soldiers, and hurts their chances for promotions. To help solve that problem, they’ve started deploying portable, electronic schoolhouses to Iraq and Afghanistan. The Deployed Digital Training Campus comes with laptops, Internet access, voice over IP, and customized Army digital learning courses. The units have been deployed to six overseas locations so far. The Army plans to have 50 by 2015.
