FORT RILEY, Kan. (AP) -- A brigade of the Army's 1st Infantry Division is breaking in new vehicles at Fort Riley.

Nearly 200 Abrams tanks and Bradley Fighting Vehicles have arrived at the northeast Kansas post over the past month and issued to units of the 2nd Heavy Brigade Combat Team.

The 1st Infantry Division says the vehicles have updated technology that improves the ability of soldiers to be aware of their surroundings.

Lt. Col. Michael Henderson said the tank can hit targets at distances of more than 4,000 meters, allowing the crew to strike an enemy without being exposed to return fire.

Additional vehicles will arrive later this year for other Fort Riley units.
