the game itself is a MMOFPS, first-person shooter with RPG elements. You gain XP for doing stuff (Killing other players, capturing bases, etc) and gain battle rankings which add different certification points you can spend to give you different certs, such as better weapons/armor usage or different vehicle control. The graphics imo dont look all too promising, but the gameplay is rather difficult yet enjoyable.
Reserves is a free version you play where the highest rank you can achieve is 6, but you never have to pay for anything apparently. Buying the game and paying the monthly fee gives you access to more stuff and higher ranks. (Rank 6 doesnt give much apparently)
Ive been to 2 bases when they've been captured by my faction and ive had a load of fun, sans being able to kill anyone

Plus theres an instant action command where you can jump right to where the fighting is. Pretty neat idea imo.
