DV it is a good point but replicating FR24 in the Military environment would be problematical to say the least. The coverage in Europe is ok provided the aircraft has the right radar (A lot do not) but the data from the US is lousy and a lot is subject to a time delay, with no info on type or destination etc. Here in Oz I can assure you where FR24 thinks my jets are is not even close to where they actually are at many points across the globe. It is not the golden app it is made out to be.
