Have to say, the flying suit, and the wings (with or without jetpack) would be a great addition to our HALO jumpers..
Imagine leaving an airplane 5 miles (or more) outside of their radar coverage and landing 5 miles or more inside their lines.. There are some radars out there that can pick up birds at fairly close range but they are VERY tailored to that mission and that mission alone, and very limited as to coverage area. Now trying to pick up a human target.. possible? Yes.. Costly? Yes.. AND your radar would have to be pointed at the right spot in the sky at the right time.
