Before the United States was directly involved in armed conflict in World War II, around 1000 U.S.  citizens signed up for duty with the British Civilian Technical Corps.  There was a demand in Britain for technically trained men to maintain specialized equipment used by the British and Allied Forces.

My father,  Edward L. Martin,  was one of those men that went to Britain and worked with the Civilian Technical Corps.  He already had a background in electronics,  so in the Corps he trained in and worked on RADAR.

His training and work with the CTC started in November of 1941 and officially ended in August of 1942,  when he was ordered to active duty with the U.S. Army Signal Corps on Reserve Commission as 2nd Lt. attached to Electronics Training Group.  At the request of his CTC superior and a TRE officer (Telecommunications Research Establishment),  he was re-assigned to TRE with the Centimeter Test Equipment Section for liaison in Great Malvern,  England.  He left Britain and returned to the United States in August of 1943,  bringing with him his new English wife (my mother) of only 3 months.

After being stationed at various places for further training,  he was stationed in Kansas where he worked on the installation of RADAR on the B-29 bombers that were headed to the Pacific Theater.  In December of 1944,  Edward was transferred to Tinian Island in the Pacific Ocean,  the base from which the Enola Gay and Bock's Car departed on the atomic bomb missions to Hiroshima and Nagasaki.
After the surrender of the Japanese,  Edward returned to the United States in early November,  1945 and transferred into the U.S. Army Signal Corps Reserve with the rank of Captain.  He served annual 15-day Active Duty tours and was promoted to Major on October 1,  1953. On August 30,  1960 he transferred to the Retired Reserve .
