Parachute doesn’t work unless the drop is higher than a two-story building. If less you will receive fall damage.
Tanks take double damage from rear hits so aim there. Tank drivers under fire, position the front of your tank in the direction of the oncoming fire or move to try and dodge it.
Repair tool can also damage vehicles. Its slow but sometimes you can do enough damage to disable the tank as the driver is expecting damage in the form of incoming fire.
Recon radio beacon creates a spawn point which your team can use to spawn. Very useful but I don’t see if being used enough.
Engineer mines: very effective. Try and plant them in bottleneck areas and try and plant them near debris/rubble to make them blend in.
Before diving out of cover take a second to look around and hit ‘q’. This will let you spot enemies and make it easier to plan your attack.
Shotguns have the ability to gain scopes, while it doesn't help the range all that much the non zooms help with aiming the shot and the longer ones are great for recon (since you can fire from the hip)
Two Stingers fired at the same time seem to disable a chopper every time.
When playing Conquest and you are dead waiting to spawn, cycle around all the flags you have possession of. Look at the graphic of each flag and see if its moving up or down, this will tell you that something is happening at the flag, ie its being taken or was under attack, spawn at this flag.
Scopes are not always a good thing, even the reflex (Non zoom) scope. A scope can limit your view as opposed to ironsights.
Flashlights can blind the enemy but they can also blind your team mates (same with lasers), keep that in mind and try and keep your flashlight pointed below head height when near friendlies and stop shining it in my face! Press ‘t’ to turn it off.
Most vehicles have a turbo option ‘SHIFT’. Jets have afterburner and tanks/jeeps have turbo. This will allow you to travel much faster and there is no cooldown on it.
Tanks: Get the thermal vision. Use it.
I think only scopes above 6x zoom glint?
The second co-op mission is great for practicing flying attack choppers/manning the gunner's seat.
Alternative tip for learning to fly the chopper: Play on an empty server for
BF2. The mechanics are almost identical. Only difference is that you have to invert the mouse in BF3, and I think the chopper is a tiny bit more sluggish in BF3. Jets are very similar too.
Recon have a piece of equipment called a T-ugs which is great to keep near a flag (out of sight) as it shows up most enemies, a great gadget.
Shout: "Enemy boat spotted" on maps with no boats.
