The Mission Training Complex at Fort Leavenworth recently hosted the Army's largest warfighter exercise in history.

But, the facility is gearing up to break that record once more as it hosts an even larger exercise this month, said Lt. Col. Kelly Brown, commander of MTC-Leavenworth.

A few thousand soldiers converged on MTC last month for the first of the two large scale exercises.

"We're training the division commanders, the brigade commanders and their staff on how to do combat operations, literally how to run or execute an operation," Lt. Col. Sarah Goodson said.

She is the public affairs officer for the Mission Command Training Program, which developed the training scenario.

MCTP is based at Fort Leavenworth.

"Warfighters are multi-echelon exercises that simulate realistic, complex scenarios that Army units must be prepared to operate in.," MCTP Deputy Commander Louis Gelling said.

He said MCTP creates computer simulated combat environments that are "realistic, dynamic and challenging."

Goodson said the scenario used during last month's training, which wrapped up Memorial Day weekend, was fictional but designed to be as realistic as possible.

"It's intended to be challenging," she said.

Multiple units were involved in last month's training. 

But, National Guard soldiers from the headquarters of the 42nd Infantry Division from New York served as the lead unit for the exercise.

"It's not often you get everybody together on the ground," said Maj. Jeffrey Oaks with the 42nd Infantry Division.

He said the exercise required soldiers to work with strangers as they would when they deploy.

Goodson said exercises such as the one conducted last month are collective training.

"We're trying to train staff as a whole," she said.

Goodson said warfighter exercises are now designed to train more units at one time, which is why last month's exercise was "full size."

The Mission Training Complex-Leavenworth covers more than 50 acres and has 20 buildings.

Brown said every building was utilized for last month's exercise.

"Every inch of space is pretty much utilized," she said.

Tents and other equipment were set up on the MTC grounds for the exercise.

First Lt. Tyler Mitchell, a spokesman for MTC, said soldiers already have started arriving for this month's exercise. They will be in the area through the end of the month.
