US Army slang meaning attacked. Initially referring to artillery attacks at night when illuminating rounds were fired to expose the target before destroying it with HE (High Explosive), Fragmentation or WP (White Phosphorous). Eventually the phrase was used to describe any intense attack on enemy positions or personnel whether it was with artillery, air strike or small arms.

Man you should have seen it, they got lit up real good!
