National Guard spokesman, Lieutenant Colonel Tim Powell says the activation of the 31st. Rear Operations Center in Jackson is part of the build-up of troops in anticipation of war with Iraq.
The unit's mission is to plan, coordinate and direct military operations, movement control and security from a rear support area.
Powell says the unit reports this weekend to Fort Stewart, Georgia, before deployment overseas, and could be activated for up to two years. He would not specify where the unit would be serving.
There are about 13-thousand members of the Army and Air National Guards in Mississippi. Powell says since the terrorists attacks in 2001, all reserve call-ups have been in support of either homeland security or the war against terrorism.
