The Tir Tairngir Peace Force is the national Army, Police, and Border Patrol all in one. They aren't 'government owned', they are an official part of the government. Every Tir citizen of a certain rank or below has to do mandatory service, which also means that every Tir citizen has biometrics on file, and that those wageslaves in the corporate compound outside Malek'thas? They're all combat trained. Sure, they're not Ghosts, but they've all got a few solid years of knowing how to kick ass. Plus, if you grew up in the Tir (and don't know a hacker who can crack an iceburg) then the government has files on you, including biometrics, and maybe even blood samples.
