In an effort to combat terrorism, Russia and India will hold an official opening of joint INDRA-2012 anti-terrorism military exercises in the Siberian Pepublic of Buryatia on Tuesday. With 50 Russian combat vehicles, participants of the exercises will carry out firing, tactical and driving drills with 500 servicemen about 250 on each side will take part in the drills. Motorized infantry and tank companies, a mortar, MLRS battalions, and a grenade launcher platoon will be represented by Russia. Russia and India have conducted five INDRA-series joint ground and naval exercises since 2003. The last such exercise was held in India in October 2010. Russia cancelled both INDRA-series ground and naval exercises last year despite an earlier announcement by the Russian General Staff that INDRA drills may be held every year and involve three branches of the armed forces.
