Serf. I'm not sure that back in 1993 your Dad would have had a very good look at a Longbow Apache, (it didn't enter service with the US Army until 1998) but even the AH64A was a quatum leap forward over what we (the AAC) were operating, and they (REME) were servicing. What everyone must realise, that although the Army Air Corps operate this machine, it is an Army capability.
