Many soldiers dream of having instant cover on the battlefield, and it looks like they might just get their wish. DARPA is soliciting proposals for BlockADE (Block Access to Deny Entry), a system that would automatically form a barrier from material stuffed into a canister 1ft by 6.5ft or smaller. If US troops needed to block off an entrance or create a makeshift building, all theyd have to do is hit a button — much more effective than sandbagging or pitching a tent, wed say.
