Force Field for Stryker

Well, sort of. It can't stop an artillery shell but could defeat an RPG attack:

A Stryker eight-wheeled combat vehicle equipped with Trophy underwent testing in support of OFT’s Project Sheriff, or the Full-Spectrum Effects Platform (FSEP). FSEP program officials seek to meet urgent operational requirements for a range of lethal and non-lethal technologies on a rapidly deployable platform. Trophy was selected in 2005 to be FSEP’s active protection solution.
The Dahlgren tests culminated in a live-fire demonstration March 30 for various US and international military dignitaries. Trophy detected, tracked and defeated an inert incoming RPG while the Stryker combat vehicle was on the move. Similar tests were successfully conducted in Israel in late February.

This could breathe new life into armored vehicles which have been having a rough go with insurgents in Iraq.
