There are many communities within the Army. These communities of different jobs (or MOS) are called branches. The following is a list of all the branches of officers of the Army. Officers are accessed upon commissioning into a single branch and come from the Military Academy, Army ROTC, Army OCS every year as newly commissioned First Lieutenants typically.
Throughout their company grade years, it's where they are assigned, developed and promoted. In their fifth and sixth year, they may receive a functional area designation within the branch and change branches throughout their career as desired or offered by the Army.
Assignments for Army Officers
Most officers will serve in positions from within their basic branch through their company grade years. Some officers will serve in a functional area or generalist positions that are not related to a specific branch or functional area after they are branch qualified as captains.
Officers serve their first eight to 12 years developing the leadership and tactical skills associated with their branch.
Following the Career Field designation, officers are assigned to positions within their Career Field (basic branch or FA) or generalist positions. This type of assignment pattern promotes assignment stability and development within a branch or functional area.
