Jacko,your spot on mate(in a way) I am sure IDM is better for air crew up at 15 grand with no known ''manpad threat'' however as the title of this thread says''from the squaddie on the grounds''point of view.From this squaddie on the ground's point of view,IDM is not really viable for me.Now of course If I was a FAC based on the english side of the Wales/England border sporting a nice pair of side burns with a nickname such as ''dinger'' IDM is perfect. For us council house FAC's that do not get on planned ops,we have to control A/C off the cuff with a ''5-line'' at best whilst we wait for the AAC to bail us out of the sh@t.
