Current Units

Mission, Training, and Capabilities 
In support of their federal mission, soldiers of the squadron train as members of M2A3 Bradley infantry fighting vehicle crews, as reconnaissance platoons, and M1A1 Abrams main battle tank crews. Additionally, the squadron has a 120-mm M120 heavy mortar platoon, a fire support platoon, a medical platoon, a signal section, a sniper squad, and a unit ministry team. When training in a traditional National Guard status, the squadron will typically complete Bradley Fighting Vehicle gunnery tables, or dismounted reconnaissance training, and tank gunnery tables, lanes. The squadron has also conducted successful training cycles providing training and validation to prepare other Nevada Army National Guard units for deployment to the middle east. Additionally, the squadron incorporates elements of stability operations, support operations, and counterinsurgency operations into larger training events. World War II 
The 2nd Battalion, 115th Engineers, an element of the 40th Division was constituted on November 3, 1928 in the Nevada National Guard and federally recognized on May 1, 1936 with Headquarters in Reno. By January 1, 1941, the unit was converted and re-designated as the 121st Separate Coast Artillery Battalion and relieved from assignment to the 40th Division. Upon the US entry into World War II, the battalion was ordered into Federal Service and on June 25, 1942 the battalion would drop the "Separate" moniker as a federal unit. It would not be until September 10 of 1943 that the 121st was reorganized into a Antiaircraft Artillery Gun Battalion and deploy in the Pacific Theatre. As continual improvements in technology progressed through the war, the unit would be reorganized as the 1st Rocket Battalion on January 4, 1945 and re-designated as the 421st Rocket Field Artillery Battalion on April 13 of that year while participating in the Ryukyus Campaign. Upon the end of the war, the 421st would be deactivated on January 15, 1946 at Ft Lawton, Washington. Postwar era 
As the dust settled from World War II, the units of the Nevada National Guard would begin to re-organize and become federally recognized. It was on January 23, 1948 that the 421st Antiaircraft Artillery Gun Battalion was federally recognized and headquartered in Las Vegas. Upon the conclusion of the Korean War, there was a triggering of unit change across the Army. With the changing times, the battalion would be re-organized as the 421st Antiaircraft Artillery Automatic Weapons Battalion on December 1st 1952. Throughout the 1950's manning across Nevada would fluctuate and unit needs changed. So on April 1, 1959 the 421st Antiaircraft Artillery, 422nd Antiaircraft Artillery and the 226th Antiaircraft artillery detachment would be merged into the newly formed 221st Artillery. 221st Artillery 
The 221st Artillery, a parent regiment under the Combat Arms Regimental System, was composed of 1st Gun Battalion, 2nd Gun Battalion, and 3rd Gun Detachment. This would be the first designation of the unit as the 221st. With the increasing cold war tensions and impending conflict in Southeast Asia, the Regiment was reorganized as an Automatic weapons regiment on June 1, 1962. After the reorganization the regiment would maintain the same structure of 2 battalions and 1 detachment until November 1965 where the outbreak of the Vietnam war would see the consolidation of the regiment to 1st Automatic weapons battalion and the 3rd Detachment. Return of the Cavalry 
With the ongoing force structure changes of the Vietnam war, the regiment would mount up in December 1967 as 3rd Squadron, 116th Armored Cavalry Regiment with Headquarters in Reno, NV. By May 1974 the unit was relocated back to Las Vegas as the 3rd Squadron 163rd Armored Cavalry Regiment. The Armor Regiment 
With the Vietnam war over, and the Army looking to add armor force restructure, the Regiment was reorganized and renamed as the 221st Armor Regiment on April 1, 1980. The new regiment would consist of  the 1st Battalion, 221st Armor and was assigned as an element of the 40th Infantry Division. In 1989 the Combat Arms Regimental System was withdrawn and the unit was reorganized under the newly formed U.S. Army Regimental System. The Squadron 

In 1995 the armored Battalion was realigned as a round out Squadron of the 11th ACR where they would fight alongside their active duty counterparts in NTC rotations. In 2007 the Cavalry Squadron would trade in its Abrams tanks for scout variant Bradley Fighting vehicles and reorganize as a Armored Reconnaissance squadron. In 2016 the squadron would leave the 11th ACR and realign as the reconnaissance squadron for the 116th Cavalry Brigade Combat Team, a National Guard Brigade out of Boise, ID.
