A plausuble source
VIRAT will be a plausible source for much intelligence that really came from other sources that should not be compromised. It will work like this:
1. get intelligence from operative or cracked encryption
2. find a reason to fly a drone or "to have" had a statellite looking in the right place
3. pretend that VIRAT found the intelligence for you.
4. act on intelligence and hope the real source isn't suspected by anyone
