Here's a picture of Bob or Big Orange Bitch as we called him. It's a remote controlled sub or a Mine Neutralization Vechicle (MNV). Use them on Minesweepers and on Minehunters before they got decommed. Has the ability to either put a charge on a moored mine or drop off an 80lb bomblet near a mine. Fun Times
We stopped in Bahrain and there was a minesweeper ported there. My buddies and I wanted to check it out, but never got the chance.
