Q

What is Mutual Support

A

Ensuring that no attacker can assault any of our positions without coming under the fires of another position, by ensuring that, if we were to lose one position, we do not lose the ability to affect that sector of fire and finally, we seek to ensure that we are able to cover the withdrawal or counterattack to/ from our primary positions
