Macgregor seems to have friends on the inside somewhere who give him accurate info on the capabilities and general disposition of Russian arms and Ukraine forces.
He then seems to extrapolate that to assume certain events, typically immediate “collapse” of Ukraine armed forces, which clearly has not occurred.
Regardless, I appreciate him because he is one of the few alternative voices to the USA state-run media. The western propaganda from controlled media is so overwhelming, its impossible to know any but the most obvious details of this war.
Fixed it for ya. Don't thank me, it's all part of the service.
