My vote for feel-good war story of the day goes to U.S. Enlists Dolphins to Aid War Effort:
U.S. Navy Captain Mike Tillotson told reporters that three or four dolphins would work from Umm Qasr, using their natural sonar abilities to seek out mines or other explosive devices which Iraqi forces may have planted on the seabed.

Tillotson said the dolphins were trained not to swim up to mines, but to place a marker a small distance away, minimizing any danger to themselves.
