Tank Turret Glitch (Historical):
In early versions of the game, it was possible to 'glitch' a tank's turret by rapidly switching seats, allowing the driver to fire the main gun while moving. This was largely patched but some variations might still exist in older server builds. Generally, it's better to rely on a dedicated gunner.

Jeep/APC Ramming:
Light vehicles like jeeps and APCs can be used to ram enemy infantry for instant kills. This is risky but effective for clearing out small groups or disrupting pushes. Be careful not to get stuck or destroyed by anti-tank fire.
Aircraft Landing/Takeoff on Carriers:
Mastering carrier landings and takeoffs is a skill in itself. Always approach the carrier slowly and align yourself with the runway. For takeoff, gain speed quickly and pull up gently. Practice this in single-player to avoid wasting valuable air assets in multiplayer.
Repairing Under Fire:
As an Engineer, if you need to repair a vehicle under fire, try to use smoke grenades (if available in a mod) or position the vehicle to shield you from the most dangerous direction. Jump in and out of the vehicle to quickly check for incoming fire while repairing.
These tricks, while sometimes situational or requiring practice, can provide significant tactical advantages and make you a more versatile vehicle operator on the battlefield.
