Mine clearing dolphins see first in battle use
Dolphins and sea lion are part of the US troops deployed in the Gulf. Tacoma and Makai, part of the US Navy's Explosive Ordnance Disposal Mobile Unit Three, are the two dolphins charged with helping clear Iraqi ports of misplaced mines. Using echolocation, the mines are found in the silt of the ocean floor. Floats are put in place by the dolphins, marking the locations. The Navy says they face no "significant" risk.
