Devil Dogs....I'm doing some research for my second novel, and I was wondering if Helicopter pilots carried call signs similar to jet pilots. Any information would help, I was former 2531 trained in 29 Stumps. Didn't have any contact with air wing. Share a call sign if you have one. Thanks...oh ps the first novel is out called "Crossing the Line." It's a border invasion/war fictional novel. It's available at www.tatepublishing.com. Thanks for the help, stay safe and Semper Fi!!
