Five Fort Hood soldiers were in “military control” Monday after they removed several pieces of ordnance to their off-post homes, leading to the evacuation of four residential neighborhoods Friday night in Killeen while authorities searched for the ammunition, the post said in a brief press release Monday afternoon.

“The ordnance was training ammunition and was not high explosive ordnance,” Fort Hood said in the statement.

“They took the ordnance from a live-fire training exercise that was conducted at Fort Hood, April 18, and the soldiers were not authorized to remove the ordnance from the post. All missing ordnance has been recovered,” the post said.

An investigation by the Army’s Criminal Investigation Command is ongoing, the post said.

Authorities responded to the neighborhoods Friday night in the northeast part of the city after they received a request for assistance from the Fort Hood Criminal Investigation Division.

During the investigation, it was determined that multiple pieces of ordnance were removed from Fort Hood and stored in different residences throughout the city.

The first neighborhood evacuated was on Splawn Ranch Road sometime around 7 p.m. followed by Hunt Drive and Transit Drive.

A fourth area on Carol Way was also evacuated.

Residents were allowed back inside their homes just after 9 p.m. Friday.
