Concentrate Fire and Squadron command icons needlessly similar?

By Destrin, in Star Wars: Armada

Just reading over the latest designer diary and it struck me that at a distance these two icons look very similar.

How large are those command dials? Could those icons be easily confused or is this a non-issue? Seems like an odd choice either way, they should have been made as distinct as possible, preferably a different colour too, just to highlight the differences

I don't think they look that much alike myself.

I agree they are a bit similar, but not so much as to be confusing.
