Another use for Grant ACW rules?

Morning all!I was having a look at Greg Novak's campaign guide (Remember the Maine and to hell with Spain - campaign Booklet IX) for this fascinating conflict over breakfast and was struck by the following quote- "This war did not last long enough to evolve tactics of its own, and was in many ways a rerun of the Civil War especially in the view of the American Army..." Has anyone used the Grant acw rules for this period?
