I think you'll find that about 80% of the US military SATCOM is commercially sourced plus the UK MOD use Paradigm under a PFI for Skynet (which is used to pipe the UK's picture - see link
Skynet 5 | PPP Forum ).
So what's your point? I'd rather be a hidden signal amongst a bunch of commercial transponders than being beamed from a military satellite that stands out like a dog's doo-dah!
So please, do tell us your concerns...
