Also here's a unique idea for navy

[xox 339]

U recruit them like any regular units and can only do that in costal provinces, then they just act like real units and are only able to move in water provinces easy lol with a image of a navy ship as their image but unit fighting remains same wait I didn't think of the last part but anyway maybe a specfic battle system for that and everything else is same as normal land units requiring and same thing basically but simply a different mechanic easy!
