I voted Critical Effects, Squadrons that Support, and "Other".
My "other" is based on my recent forays into Star Wars Legion. Given that most of my tabletop wargaming experience is with fleet-based naval games, I tend to use my infantry units like they are squadrons of ships. Which means I put them out in the middle of the battlefield and don't always remember to use terrain for cover. In naval games your ships are going to take damage. In a lot of cases they will still be combat-effective (up to a point), but infantry squads (at least in SW Legion) aren't so hardy. So to me that also is a hallmark of naval-themed games--probably everything you put on the table is going to get shot at and damaged, but in many cases will still be able to maneuver and return fire.
Hope that makes sense...
