Soldiers of the 219th Engineer Brigade provide various supportive duties to other Army units, including construction, engineering, and mechanical work on other Army projects.

The 219th was originally activated in 2007 as the 219th Battlefield Surveillance Brigade, one of ten other self-sufficient battlefield surveillance brigades that were activated during efforts to reform and modernize the US Army.

Its original mission was to improve situational awareness for commanders at division-level or higher.

Since its activation, the unit has taken part in overseas tours to Kuwait, Qatar, Jordan, Iraq, Afghanistan, and has independently conducted various humanitarian missions in the United States and in other nations throughout the world.

2-150th Field Artillery Battalion is headquartered at Bloomington, Indiana.
