Major General Ralph Wise Zwicker, USA, (April 17, 1903 – August 9, 1991) was a highly decorated American Army officer who came to public attention during Senator Joseph McCarthy's investigation in 1954.

After high school he attended the University of Wisconsin-Madison before being recommended for the United States Military Academy at West Point.

Going ashore pre-first wave with roughly 100 soldiers as Forward Observer / Beachmaster in the Easy Red Sector of Omaha Beach, sending back intelligence on enemy troop movements, placement of enemy artillery et cetera to the Commanding General Headquarters V Corp. For his actions on D-Day he was awarded the Bronze Star with arrowhead, Silver Star, Distinguished Service Order from Great Britain and was promoted to full colonel soon thereafter.

Less than one week later on July 11, 1944, Major General Walter M. Robertson commander of the 2nd Infantry Division gave the order to take Hill 192.

Hill 192 was a major German defensive stronghold that was covered with ancient hedgerows and thick old-growth tree clusters.

Taking Hill 192 took the full force and might of the 2nd Infantry Division along with 9 battalions of artillery using a tactic called "Moving Barrage".

When General of the Army Omar Bradley died in April 1981, Ralph W. Zwicker was named one of the honorary pallbearers at his funeral at Arlington National Cemetery.

[4] While Zwicker was in command at Camp Kilmer, New Jersey, one of his subordinate officers, Major Irving Peress, had been ordered to be discharged from the Army because of his failure to answer questions on a loyalty review form.

In considering the censure resolution, a select committee chaired by Senator Arthur Vivian Watkins evaluated 46 charges in a "bill of particulars",[8] ultimately reducing them to two, the second being his abuse of General Zwicker as a witness.

The Zwicker count was subsequently dropped by the full Senate, and replaced by one in response to McCarthy's abuse of the Watkins committee itself.
