In United States Army units, a headquarters and headquarters company (HHC) is a company sized military unit, found at the battalion level and higher. In identifying a specific headquarters unit, it is usually referred to by its abbreviation as a HHC.While a regular line company is formed of three or four platoons,a HHC is made up of the headquarters staff and headquarters support personnel of a battalion,brigade,division,or higher level unit. As these personnel do not fall inside one of the regular line companies of the battalion, brigade, or division, the HHC is the unit to which they are administratively assigned. The typical personnel strength of an average HHC is 80 to 110 personnel.
Inside a battalion HHC, the headquarters staff will usually include the following key officers and primary staff officers:

Depending on the unit,extra support officers will round out the staff,including a medical officer,a member of the Judge Advocate General's Corps or legal advocate,and a battalion chaplain.This is often collectively referred to as the (“special staff").In addition,there are essential non-commissioned officers and enlisted support personnel in the occupational specialities of the staff sections (S1 through S4 and the S6),and a battalion Senior Enlisted Leader.This is usually a command sergeant major who is principal advisor to the battalion commander on matters regarding enlisted personnel.Additionally,the HHC will contain further personnel assigned to support and sustain the mission of the battalion headquarters,including members who work maintenance and motor pool,field feed and mess,and supply roles.
The HHC itself will be commanded by a company commander.This is usually a captainwho is supported by a company executive officer.This is usually a first lieutenant.Finally there is a company first sergeant as the Company Senior Enlisted Leader.All personnel in the HHC fall directly under the administrative command of the HHC commander,but in practice,the primary and special staff officers report directly to the battalion commander,and while the battalion commander is administratively assigned to the HHC,he or she is the HHC commander's higher commander and thus the HHC company commander operationally answers directly to the battalion commander.The mission of the HHC commander is to run the administrative and soldier training aspects of the HHC, and to support the battalion primary staff by facilitating the environment in which they operate and in turn support the battalion commander in commanding the battalion.
At the brigade and division level,a HHC in the Division or Brigade is similarly constituted of the brigade commander or division commander,his or her staff,and the support elements,but the ranks of the staff and support personnel are typically greater to reflect the greater level of responsibility at higher echelon units.However, the company commander of a brigade or division HHC is usually still a captain.
In keeping with the long standing practice of referring to company sized artillery units as”batteries" and company sized cavalry units as”troops,"the headquarters company element of an artillery battalion or higher is referred as a Headquarters and Headquarters Battery (HHB),and the headquarters company element of a cavalry squadron or higher is referred as a Headquarters and Headquarters Troop (HHT).Additionally,some high level headquarters elements for special units are not company sized and are therefore referred to as"detachments;"as a result,these units are formally referred to as Headquarters and Headquarters Detachments (HHD) depending on the type of Unit.
