– Breaking Defense – Just nine months after hosting the biggest multinational mine-warfare exercises “ever” to be held in and around the Persian Gulf, the Navy’s 5th Fleet and its foreign partners outdid themselves with a second, even larger wargame. More than 20 nations participated in September’s International Mine Counter-Measures Exercise 2012, collaborating against fictional ecoterrorists whose capabilities were suspiciously similar to the real-world arsenal of Iran. This month, 41 nations and some private-sector companies participated in IMCMEX 2013, which despite the name expanded beyond minesweeping to practice protecting civilian oil tankers, oil rigs, ports, and even desalinization plants as well.
