<Could get you through those TAs or the National Gaurd checkpoints to freedom

Unless you are planning on wearing a full uniform and have the military jargon and info to carry it off, you are going to scream 'fake' to any military you meet. Good way to get arrested. A 'soldier' turning up with no companions, no weapons and no ID is not going to last long.
No TA or National guard units have ever tried to force people not to go to 'freedom' (whatever that means. you think they are going to arrest liverpool or somethiong?)
This is a way of creating a real problem to avoid a non existent one.
