Who will talk about the difference and gameplay between Battlefield 2 and Battlefield 3? Thank you

Battlefield 3 squad mode exists, with four people as a squad, but there is an extra squad special prop, and each player can be equipped with special props, such as ammunition, grenades, bulletproof vests, etc. The effects are different. There are only two camps, one in Russia and one in the United States. The control of vehicles and weapons are quite different. The weapons of various arms have also increased. Anyway, there are many ways to play.
