For more information about this weapon in Mud and Blood 2, see BAR.
The Browning Automatic Rifle (BAR) is a well-rounded LMG that bears more similarities to heavier assault and battle rifles than it does to the other LMGs due to its small mag size, low bulk (for an LMG), high damage, low rate of fire and good range. As such, it is ineffective at suppressing enemies, but makes up for this with excellent killing power and range. Its heavy recoil is also partly negated by its slower rate of fire.
This relic of a gun was documented to be used well into the Vietnam War. It was not until this conflict that the BAR was finally succeeded by a new class of automatic weapons. Pre-dating any of the assault rifles of this conflict, the BAR had been augmented over countless conflicts (being the M1918A2 by this stage). A far-cry from it's initial role as a supporting fire weapon, the US Army had opted instead to deploy more units per platoon. This can be seen by the addition of a forward grip to the weapon for improved aggressive handling. Many special-operations units with weapon choice at their discretion opted to continual using the BAR, due to its well established performance and low malfunction rate. It was used as an assault rifle role as many operators opted to forgo the bipod to reduce weight (unlike other conflicts they did not remove the flash suppressor due to the prevalence of night fighting during Vietnam). Its inclusion in Recon is highly accurate and its stats reflect many of these factors. Regardless, the BAR was in the process of being phased out and was eventually relegated for use in arming friendly native forces (This remained true even after Vietnam).
