For simplicity's sake in this article, the CIWA will be referred to as the CIWA, but technically it goes by another name; the CIWA-AR. CIWA-AR stands for Clinical Institute Withdrawal Assessment - Alcohol, Revised. The assessment has been revised to stay current as treatment for alcohol addiction, alcoholism treatment and withdrawals have been studied over the years.
The Continental Army of the American Revolution was mainly composed of infantry, with very little artillery and cavalry. In 1774, on the eve of the Revolution, some colonies had volunteer mounted units of troop size, but these troops were as much social organizations as military commands.
In 1851 the army eliminated the old dragoon cap and approved a pair of crossed sabers as the new insignia of dragoons to be worn on new style caps (shakos). In 1855 the U.S. Army created mounted units that were actually called cavalry. During the period 1858-1861 both Cavalry and Dragoons wore the crossed saber insignia. Dragoons wore the insignia in the way more familiar way oriented edge up. Cavalry wore it in a way that we might call upside down with the edge downward. In August 1861 it was decided to rename dragoons and mounted rifles as cavalry and all of them wore crossed sabers edge up. During the Civil War cavalrymen wore crossed sabers on the front of the dress (Hardee or Jeff Davis) hat and either on the top or sometimes the front of the forage cap or kepi.
