Battle Assembly

These training activities were formerly referred to simply as "drill" or "weekend drill", but according to former Chief of the Army Reserve, Lieutenant General James R. Helmly, the term was changed in 2005 to emphasize the need for Army Reserve soldiers' training to focus on continued preparation for fighting the Global War on Terrorism.

[1] During the Korean War (1950–1953), the United States Congress made significant changes to the structure and role of the Army Reserves.

The soldiers that attend battle assembly (weekends) are compensated at a higher rate than active duty components.

Conversely, members of the Individual Ready Reserve are not required to attend Battle Assembly or Annual Training, but remain committed to military service obligations and may be recalled to active duty as directed by the President or U.S. Congress.

Their duties typically continue until Sunday evening, but may end earlier at the direction of the unit's commanding officer.
