Very nice book, I always enjoy publications from Osprey. This book was well written and each section was broken up concisely. I learned a lot that i did not previously know about the Su-25. Many things from, prototypes, different models, weapons, development, and real stories of combat. There were also many great pictures, some real others renderings. The amount of technical information provided in the book was quite vast and impressive. I really enjoy these books by Osprey and this is no exception.
