This time, however, the exercises involve other big boys of NATO. At the invitation of the US Air Force (USAF), the Indian Air Force (IAF) is participating for the first time in multi-nation combat exercises, equipped with six Jaguars, two heavy lift IL-76 transport planes, two IL-78 tankers and a 200-strong team. Cooperative Cope Thunder 2004 is a tough test with multiple mock scenarios of assassinations, unrest, rescue and other emergencies. In other words, an imagined "real" world will come alive for 15 days with crises erupting and governments toppling. At the height of the battle, up to 70 jets could be flying in the same airspace at one time. The IAF will be part of the "Blue" forces or the good guys, fighting off the "Reds" or the bad guys. No ideological compulsions here, the colours are simply a tradition coming down from World War II. The USAF has teams on both sides. Ground forces will be "White" or neutral, doing the umpiring and ensuring everyone’s safety.
