[Mass Combat] Should F/Ranged units count as Marine when on ships?

Opinions?

If you're house-ruling anyway, you'd probably want to account for cavalry being considerably less useful when unable to use their mounts.

I can't help thinking that we should have rules about using units as make-shift units of something else. Infantry, musketeers, etc. can function as make-shift marines, but not as well as dedicated marine units. Cavalry without horses are make-shift infantry and if they're trained dragoons, they'll be better infantry (but worse cavalry) than cavalry which didn't spend time and money on such training. A unit of pretty much anything can be make-shift irregular infantry, troop quality as engineers or artillery doesn't necessarily translate to being good infantry.

And no, I don't have a ready-made solution. But in my games, I'd eye-ball any elements that were otherwise unable to contribute and judge what other troop type they could function as (albeit make-shift ones).
