Let me explain how it works in BF2142: When loading each match, any player who had passed a certain level (I don't remember exactly which) could apply for the role of commander. Once they obtained the role, that player was not part of any fireteam. Among their gadgets, they had a tablet from which they managed various functions, including: giving orders to the team leaders of each fireteam (mostly attack, defend, or monitor a specific area), launching missile strikes, supplies, UAVs, and counter-UAVs to disrupt the other commander's UAV. They did all this by stationing themselves, for strategic reasons, in their own headquarters, where all the weapons needed to launch support were installed (missile launchers, radars, radios, etc.) which could also be damaged and then repaired by an engineer or permanently destroyed. We are obviously talking about the CONQUEST game mode. The fireteam team leaders could also ask the commander for orders, requesting the launch of supplies, launching ground vehicles, UAVs, or missile launches. All these mechanics were rewarded with bonus points that were added to the total score that determined the final match standings, obviously only if the orders were respected.
Imagine having a coordinator directing the attack in a faction with more than three friends.
