MBR meaning in Military and Defence ?

Answer:

What is Main Battle Rifle mean?

A battle rifle is a service rifle chambered to fire a fully powered cartridge.The term "battle rifle" is a retronym created largely out of a need to better differentiate the intermediate-powered assault rifles (e.g. StG-44, AK-47, M16, AUG) from full-powered rifles (e.g. FG-42, FN FAL, M14, H&K G3) as both classes of modern firearms have a similar appearance and share many of the same features such as detachable magazines, pistol grips, etc. Battle rifles were most prominent from the 1940s to the 1970s, when they were used as service rifles. While modern battle rifles largely resemble modern assault rifle designs, which replaced battle rifles in most roles, the term may also describe older military full-powered semi-automatic rifles such as the M1 Garand, SVT-40, Gewehr 41, Gewehr 43, Type 4, FN Model 1949, and MAS-49.
