Stamina is a mechanic in Battlefield 2 and Battlefield 2142. Stamina is a measure of the player's physical capability. Actions such as sprinting and jumping will drain the stamina over time. If the player runs out of stamina, the player cannot sprint or jump.
The amount of stamina the player currently have is shown as a bar in the player's HUD, alongside player's health.
In Battlefield 2142, players have option for different body armor classes for each of their kits. Light armor provides full stamina while heavy armor reduces it by half.
The Sprintcor 20 Enhanced Endurance unlock permanently increases stamina, while the Staminar 9 Recovery System unlock permanently increases regeneration of stamina. Players have maximum stamina with Sprintcor and light armor.
