I am a proponent of such units but for every one "dedicated" individual hired, probably 200 wanna be's give such activity a black mark. (The Afghan leader insisted on "white" caucasians(?) so he could tell if a local got close) TTC
Back years ago when you and I were in deeper than we wanted to be, all we wanted to be was "OUT". Seems today people are so lost, far more than 47 years ago. I went in for the free education. I'd imagine many still do today, but the educational benefits are much lower now by comparison. I lived off VA benefits while in school. And it got me out of the cotton mills.
Seems now though, everybody wants to be somebody - and its' gotten darned artificial. Used to be we could make our own future, and we had the patience and determination to follow through.
Now it has to be instant gratification. Certainly not everyone - good guys still exist.
As to the private armies, I agree with them though I wouldn't be involved = who the heck can you trust when it's all about money with no allegiance.
Hired military mercenaries. Had them in Iraq. Then they were dismissed due to their ego's and ignorance. Paid 3-4 times that of our soldiers. It's all about the money. Without going on a rant. I'll just say, I saw the money machine first hand. In so many levels.
