Note: This is only effective against enemy ground units. This is difficult to do and 
requires many practice runs. If you find yourself with a missile being shot at you, 
try to boost to the nearest enemy ground unit. Then, slow down and make sure not to 
go past the ground unit. As soon as you see the missile closing in on the radar, 
quickly boost towards the ground unit, and time it so that the missile will go past 
you and into the enemy unit. This is possible to accomplish with a lot of practice, 
but is extremely difficult to time correctly. Try using it on enemy ships first, as 
they are much larger than tanks. Then, work your way down the size scale until you 
can use it against all enemy ground or sea units. This will save you missiles if 
your ammunition is low, or you need to conserve as much as possible as in missions 
16B, 12B, and 9.
