The Training system is a feature introduced in, and unique to, Battlefield Play4Free. It is similar to the specialization system of other installments, but differs in that instead of acquiring experience in a Kit to unlock a specialization, every time a player ranks up with their soldier, they can increase their level in a training option for that soldier.
The training system allows the player to acquire abilities, passive effects, or extra equipment as they increase in rank. Each time the player levels up, they gain one training point, which they can then spend on a particular equipment piece, skill, or passive effect. There are three tiers, with the second tier of each category requiring five points spent on the first tier to unlock.
The training system offers two different types of training expertise:
- Equipment Expertises focus on a soldier's available equipment they are able to take with them in to battle. Much of these options level up a player's ability to use equipment like Ammunition Boxes, Medkits, or the Repair Tool, while others allow a player to fly aircraft, use secondary weapons on tanks and APC's, or increase overall ammunition.
- Combat Expertises focus on increasing a soldier's ability to find and eliminate targets, along with moving around the battlefield. Many options level up a player's awareness to nearby enemies and explosives, while some allow the player to move and climb faster.
