The Battlefield 2 total conversion historical realism modification "Battlefield: Korea" deals with the Korean War (1950 - 1953), which is also known as the "Forgotten War".
The Mosin–Nagant (Russian: Винтовка Мосина, ISO 9: Vintovka Mosina) is a five-shot, bolt-action, internal magazine–fed, military rifle, developed by the Imperial Russian Army from 1882 to 1891, and used by the armed forces of the Russian Empire, the Soviet Union and various other nations. It is one of the most mass-produced military bolt-action rifles in history with over 37 million units having been made since its inception in 1891, and, in spite of its age, it has been used in various conflicts around the world even up to the modern day, being plentiful, cheap, rugged, simple to use, and effective, much like the AK-47 and its variants.
In the years after World War II, the Soviet Union ceased production of all Mosin–Nagants and withdrew them from service in favor of the SKS series carbines and eventually the AK series rifles. Despite its increasing obsolescence, the Mosin–Nagant saw continued service throughout the Eastern bloc and the rest of the world for many decades to come. Mosin–Nagant rifles and carbines saw service on many fronts of the Cold War, from Korea and Vietnam to Afghanistan and along the Iron Curtain in Europe. They were kept not only as reserve stockpiles, but front-line infantry weapons as well.
The PU scope (ПУ, прицел укороченный, 'Scope short-cut' in comparison to PE scope) is a sniper scope of Soviet manufacture, widely used on the Mosin–Nagant and SVT-40. The scope was fixed at 3.5 power magnification. The reticle could be adjusted vertically for range, from 0 to 1300 meters. Horizontal adjustments for windage were also provided.
