satellite definite very accurate but is of course limited
signals intercept definite probably coded have the Brits broken it . Even if they havent there are a number of things that can be deduced
Mi6 probable I would be very surprised if they have not been there since at least 2014
22nd brigade slightly possible you never know where they are . There are still stories that they were in Veitnam added into Australian and New Zealand troops and then on a plane back to Britain who knows
