FORT CARSON, COLO. -- Reporter: Chris Buckley

Police shot a Fort Carson soldier at the post after reports he was acting erratically Thursday.

According to Army officials, Military Police and Department of the Army civilian police both responded to the officer's home after a 911 call from a neighbor around 11:45 a.m.

Officials said the soldier  lives in the Chocktaw Village neighborhood but declined to give an exact address.  Five officers entered the home.

"And as the officers entered the residence, he moved towards them in a threatening manner," Col. Robert McLaughlin, Fort Carson Garrison Commander, said. 

Fort Carson officials said the soldier was armed with a knife at the time.

A DA civilian officer shot the soldier.  He was taken to Memorial Hospital with non life-threatening injuries.  No one else was hurt.

"The safety and welfare of the community, of our soldiers and families is of the utmost importance to this command," McLaughlin said.  "The quick reaction of our first responders demonstrates our capability and our commitment to protect the community. We have a great relationship with the front range community and their first responders."

All that's known about the soldier is that he was a member of the third brigade combat team. That brigade is currently overseas.

The Army's Criminal Investigation Division and the FBI are heading up a joint investigation into the matter.  Because the investigation is ongoing, a lot of questions remain unanswered.  It's unclear if the soldier will be charged with a crime.

Army officals said it's standard procedure for any officer that fires a weapon on-duty to be put on administrative leave until the investigation is complete. They've also informed the Fort Carson community about the situation.

"It's very important with regard to life, health and safety when we have an incident like this on the installation that we inform those on the installation and in the community of what has happened," McLaughlin said.

Officials do not know how long the investigation could take.
