Sample 1:

Second version with an October 2002 production date in green dominant cordura.  Ranger Body Armor (RBA) vests were first used in Somalia in 1993 and were used until ~2005 by Army Special Forces and by the 173rd Airborne Division in Operation Northern Delay.  These vests were originally made for the 75th Ranger Regiment.  The first version had no back plate pocket, which was added after Somalia.  The vests accept PACA style soft body armor panels as well as hard plates in the outer pockets.  The “chip” in the front panel is to allow a rifle to be shouldered.
