TWO VIETNAM NAM BOOKS-US ARMY INSIGNIA/AIRMOBILITY

The first book is U.S. Army Insignia by James Mc Duff published in the 1970's? The whole book is on theater made patches for the various units. He shows variations to the hand made patches, interesting reading. The second book is the Vietnam NAM studies published by the Dept. of the Army in 1973 covering Airmobility 1961- 1971. The former owner highlighted several pages but did not list why. The cover is dirty from use rest is in great shape. Condition insignia like new, Airmobility good
