That there is what I call a worthwhile post. I have thousands of books on my book drive, many military PDFs such as the complete Osprey collection (yes, every book they ever published) as well as many, many others in epub/pdf. Very happy to see that there are several here I don't have, and am adding right now to my collection. Some fantastic material here that isn't all the easy to find online, or for free.
Many thanks ROC.
