What I want to see added are icons for unfinished buildings and amphibious units. This would help recognition.
A half-dome/half-diamond would work nicely for amphibious units and could even have the dome representing if it's an underwater or overwater capable unit.
Something like this:
For the unfinished buildings/experimentals these were what I came up with. I think the experimental one works really nicely, it's clear and visible on both dark and light backgrounds. For the unfinished buildings I first tried out the blacked out corners and while that works perfectly well on light background it's quite unclear on dark backgrounds. I then made lines cutting the corners and because it leaves army colour visible in the corners it's still recognisable even on darker backgrounds.
Biass noted they had tried something similar somewhere:
I made some concepts and sadly there isn't space for the wave symbol in the unit icon. The two symbols would have to become so small making sense of which unit is direct fire, anti-air, shield or artillery becomes nigh impossible.Either way, the idea was proved to not be so good, what might look good on paper expanded to 200% would only be needed in the niche scenario where amphibtanks/tanks were mixed together on land, because of course regular tanks cannot go onto the water, and a faction is not seraphim, and then the apm and constant camera movement will make what is reality is just a few pixels moved over a lil too hard to distinguish. Not only that, but it would garble up very amphib factions such as aeon t1 and cause a lot of extra effort to identify units if the icon change is even noticeable at all.
If you had to change something, make it not the currently very well made set of four shapes (buildings, land, air, sea) and something like the element actually inside the shape, that is made for more advanced identification already. adding a small wave or another simple lineart would work far better without reworking what was already a really well made part of supcom's ui design, you can still easily see that a land unit is a land unit, and then if you needed to see what was a floaty boi for whatever reason you could check the inside, it's been proven to work for arty, aa, etc and should work here if it's well made.
