Officers of the Union
The Officers of the Union are the presiding officers of the five major branches of the Rensselaer Union; the Student Senate, Executive Board, Judicial Board, Graduate Council, and Undergraduate Council. The Head Cheerleader was a former Officer of the Union before the post's abolishment in the 1969 Union Constitution. Two of the officers of the Union, the Grand Marshal and President of the Union, predate the modern Rensselaer Union, whereas the other three came into being with their respective branch.
