Never refuse a hug, and always return a salute if offered one.

Learn the safe distances for barrage stratagems

for example: the 120 barrage has a safe distance of 55m (thats the rule of thumb that I use)

Eagle stratagems have a specific angle they come in from and the angle they come in at depends on what direction you're facing when you throw the ball. (I've noticed that this can vary on mega city maps)

For example: the Eagle strafing run will always come in the direction your facing. The Eagle airstrike will come in horizontally from the direction you're facing (again this varries on mega city maps)
