pencil in Nav Map of silent hunter 4

[tscalvert]

There are 2 pencils in the nav map of silent hunter 4, the smaller one states it is for ... SELECT COMBAT UNITS. I`m trying to figure this one out but having trouble. Can someone help me get in the right direction. thanks in advance.

One of the pencils was added when the u-boats were added. It's only useful for the Germans, so I don't know any details about it.

Thanks for your response. Your info at least helps me to know where to go if I want to continue looking further into this.
