Can someone explain to me in Layman's term what is Scoot & shot on a VTOL and how do you use it?

X = movement value of the VTOL

If you decide to fire, perform the following:

X-12 = how many inches you can move around before and/or after you fire at your target.

Example:
SS Balac has a 16" range. It has a 17" movement.

17 - 12 = 5

It can move 2" forward, fire, and scoot 3" back or out of the way.
