A is the lead escort. Note my AOB is making me a very small target.
B is the next closest escort. Once A has passed a bit I will switch the focus of my AOB to B, if possible.
C shows where the outside row of the convoy is going to be when they reach my position. As you can see I'm just about in it's path already. Even at 1.5 knots I can easily move out of its path when the moment is right and proceed towards my target inside the convoy.
Oh, and of course - I'm under water. : /
