According to a photo released by Britain’s Ministry of Defense, the British Royal Navy used a Garmin eTrex Legend to confirm the location of the ship where 15 British troops were taken by Iranian forces. The above photo is taken from inside a Royal Navy chopper, hovering over the scene of the incident. The latitude and longitude coordinates can be seen on the eTrex’s display, confirming the exact location of the ship – a matter of some dispute by the Iranians.
