28th Signal Battalion (United States)
28th Signal Battalion is a battalion of the US Army formed on 12 September 1908 in Pennsylvania as a National Guard unit at Pittsburgh as Company A, Signal Corps. It served alongside the regular army under Federal control several times, most notably during World War I, World War II, and the Cold War from 1950. Its home area is Southwestern Pennsylvania.

As a National Guard unit, its main purpose is to assist the State Government in response to events which require more manpower or specialist skill that traditional first responders cannot provide, such as in large scale riots, and natural disasters. However, when in Federal service alongside the regular army its main purpose is to provide communications support to the units it is attached to.

In November 1993 the battalion was issued new equipment. Mobile Subscriber Equipment (MSE) is the Army standard equipment for corps and below.
