Battlefield 4's multiplayer has one hundred and forty ranks, with each rank holding five sub ranks with roman numerals. There are forty-five ribbons which are unlocked by completing specific actions. Earning one ribbon fifty times awards a medal with forty-five Medals in total in the base game. Service Stars are awarded after earning enough experience progression for that object. There are one hundred and thirty available service stars, each capable of being earned one hundred times.
All classes featured in the previous installment return in Battlefield 4, although with a few changes. Carbines have become all-kit weapons along with Designated Marksman Rifles (DMRs) and can now be utilized by all classes, as with pistols and shotguns.

Battlefield 4 features a total of ten maps in the base game, all of which are available on all seven gamemodes in the base game. Two of them, Obliteration and Defuse, are new additions to the series, putting further emphasis on team-based play. Additional maps and gamemodes were added through expansions.
The game features over fifty available vehicles. Many vehicles come with specializations unlocked so as to better balance play between newer and older players. Naval combat has been heavily improved. Waves now play a factor in how boats move, requiring players to compensate when engaging enemies.
Unlike previous games in the series, Battlefield 4 allows the owners of rented servers to choose which factions can fight one another on which map, as well as which deployment they may use on the map.
