In multiplayer 99% of the time you just run. If you're lucky, then among 128 people who want to get into a tank or a helicopter, and become a driver and shooter of a tank from a cannon or helicopter, but no, most often you just run around huge maps for 2 hours. The balance of vehicles is very minimal, the developers of BF4 left, and after them other developers began to release non-playable games, even in BF5 you have to wait a very long time to become a tank driver, the developers of BF4 did not allow such a thing for themselves and the tanks were always available at any time, and so same helicopters and planes and other equipment.
