For those of you who understand French this might be a quite interesting online TV-channel. Launched by the well known RAIDS magazine you have about 6 dozen military related documentaries online. You pay 4.99€ per month by credit card or PayPal and it's very easy to terminate the contract that runs on a monthly basis. I have watched a few of the documentaries and I have to say that I was really surprised about the quality and the in-depth information.
