Not quite. The idea of the *fencerails* is for the PG7V warhead to pass between the slats and get dented, which will dead short the firing circuit between the piezo crystal in the nose and the detonator ans booster at the base rear of the charge. THe PG7 uses the outside metal body as one conductor, the copper or aluminum charge liner as the other. If they touch, the round is a dud.
The chainlink used in Vietnam caused the warheads to not detonate about 50% of the time. Problem is, the Stryker tops aren't covered, and there are plenty of roofs in Tikrit.
It's better than no armor at all, and it'll make a handy rack for rucks anmd boxes of MREs. But forget about transporting Strykers in-theater by C130 now.
