I am militarily challenged but would like to understand my Father's experiences 1944/5 after landing on Omaha Beach with RAF support staff and have many questions. A few to start: Family legend indicates that his Unit landed on Omaha on D Day + I. However on the RAF Omaha Beach site a plan made earlier in 44 said they were to land on D. Day +3. Is there any way of confirming when his unit landed? Would it have been attached to a specific American Army Unit? What would conditions on the beach be like at that time compared with the carnage on D Day? Recently found his tiny diary for 44 ( June pages missing). He frequently mentions numbers like 15074 or 15087 which again I now believe are other Support units. Does anybody know how the Q units relate to these units? How closely did units like my Dad's work with other non-RAF troops? There seem to be many types of Units with letters after them J, Q etc. What did they signify in terms of different function. If anybody can help me from their own knowledge or a reference to a specific source It would be greaty appreciated. Trying to ensure his experiences are not lost to the next generations in our family.
