@AtrikPossibly a garrisoning level as a bar (10 out of 30) ? This could help identifying which of the vessels to use preferably for attacking, or if being attacked which are most costly when sunken.
A similar feature could be interesting for fortresses and towers.
We had a OOS today with a lot of players and specs OOS. I wasn't OOS so heres my logs.
OOS Players: breakfastburrito_007, Atrik, Decger (1623), terry_boucle (1507), erictommy01 (2000)

I like the idea but would be hard to display icons if there are many different units garrisoned. Also might be confusing if you have icons for training, but also for garrison..
There is also a limitation where it's not possible to display text (or numbers) for the while this feature is in a mod.
