Area Attack Command
Area Attack is a permanent command (i.e. does not end unless canceled by the Stop command or another command is issued) exclusive to bombers. It causes the bombers to attack any targets in the area or the ground if no targets can be spotted. The shots are distributed evenly over all targets in the area or the area itself.
The Default hotkey for Area Attack is Alt + A. It cannot be modified by the Ctrl or Alt modifier. It cannot be issued to non-bomber units. If issued to a bomber that has landed on the ground, it will not take effect until the bomber has taken off.
Area Attack can help put pressure on areas undefended by Anti-Air without demanding large amount of attention. Its use after Anti-Air becomes prevalent is highly advised against as the planes will be split into a steady stream rather than a large burst, making then far more vulnerable.
