The US military wants walls that automatically pop out of cans

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 they’d have to do is hit a button — much more effective than sandbagging or pitching a tent, we’d say.

At the least, DARPA wants BlockADE designs to slow down intruders with axes or saws. However, the agency is also looking for as many extra features as it can get, including “ballistic resistance;” ideally, soldiers could take cover behind the insta-wall in case of a firefight.
