What is the attack order command in Battlefield 3

In Battlefield 3 multiplayer while as a squad leader, the player can issue an attack order to their own squad by aiming the cross hair over an objective, such as an M-COM station in Rush/Squad Rush, or a flag in Conquest and pressing the default command button for the action. To learn the command for issuing an attack order, open the 'Options' menu, then go to 'Controls' and select 'Button Controls'.

Note: Sometimes you cannot issue an attack order is you are in too close proximity to an objective or the objective is out of line of sight. In these cases, move away from the objective and in line of sight and try again.

Note: Attack and defend orders are issued using the same button/key. Attack orders apply to the attacking team/squad in Rush and Squad Rush. While the defend orders apply to the defenders in those games. For Conquest, attack and defend orders are issued corresponding to whether the flag is under enemy or friendly control.

The default button is 'Select' for PlayStation 3 and similar button for Xbox 360.
