Arden Hills Army Training Site

Formally known as the Twin Cities Army Ammunition Plant, the facility produced over 16.5 billion rounds of small-arms ammunition for World War II, the Korean War and Vietnam conflict. The site of the Minnesota National Guard Training Area is currently occupying the acreage used for storage and ammunition testing. Although some structures of the Twin Cities Ammunition Plant still exist, the Minnesota National Guard Training Area, known as AHATS, is separated and is managed by separate agencies.

The Arden Hills Army Training Site (AHATS) is a military training area under the control of Minnesota National Guard and the Minnesota Department of Military Affairs. While the land is federally owned, it and all activities are managed by the DMA through the Camp Ripley Operations and Range Control Office.

AHATS is considered Camp Ripley south, and the rules that apply at Camp Ripley apply at AHATS. Absolutely nothing is different except that there is no live fire, blank ammunition and pyrotechnics.

Units will request the use of AHATS by submitting an ATS Form 23 no later than 30 days prior to the requested date. A full time (AGR or Technician) NCO of the unit requesting a training area is required to attend a Training Area Coordination (TAC) briefing at the Arden Hills City Hall with the TAC within three months of using AHATS. This NCO will then act as the Point of Contact with the AHATS TAC.
