Do not confuse rank with pay grades, such as E-1, W-2 and O-5. Pay grades are administrative classifications used primarily to standardize compensation across the military services. The "E" in E-1 stands for "enlisted" while the "1" indicates the pay grade for that position. The other pay categories are "W" for warrant officers and "O" for commissioned officers. Some enlisted pay grades have two ranks.
