You know what, I just did some cut and paste editing in paint and the size scale I think needs to be made a bit different, army a touch bigger and navy a touch smaller, but these can be made to look quite good side by side with army in the center guard on the left and navy on the right. I guess that's about it, I'm out of suggestions now. Best of luck and happy bullet trails.

Hmm, what about having the color transition be lateral instead of vertical, and what sort of fade transition did you use? But yeah I can see how difficult that would be, probably better off using the cresent moons if anything.

thanks for the feedback

viewing them together is just for comparison purposes. they aren't really meant to be seen this way, although i suppose they would in some settings. it is the same civ, though.

i tried the color transition before with the guard like you mention, didn't come out very good though.

I somehow picture army as terran, navy as dwarven or generic alien and guard as elven or protoss. As for the fonts, taken on their own each logo looks pretty great. Regarding making them look good side by side I might suggest using bird stylized feathers as flanking brackets around the text. This assumes of course that they are military branches of the same world or nation. I suggest the feathers because all three logos featture wings. I would also suggest having the feathers start with the color and "style" of the guard at the tips then flaring out into the color and "style" of the navy before thining and fading into the color and "style" of the army at the base. My suggestion does consider the current order of the logos, swapping guard for being in the middle would work too although I'm not sure how "natural" the color progression would look.

some things to consider:

the order of the pictures doesn't matter, as this image is just for comparison purposes

the Phoenix Army has a heavy emphasis on airborne deployment via gunships. hovertanks and actual ground units are used only when that isn't the most effective option, such as when a more defensive war needs to be fought rather than the usual blitzing. so an attacking bird kind of fits. there's also no air force, as it is split between the army, which handles atmospheric flyers, and the navy, which handles space fighters and bombers

guard is actually analogous to the coast guard, and uses ships much more than troops. they would rely on boarding operations much more than the Navy, though.

that being said, i may still redesign the Navy to be more birdy.

These all look good, but the Army one in particular is incredibly badass.

yeah, each font is designed more for its respective logo than any concern for fitting with the others.

i can't really think of many cases where i'd be putting these logos right beside each other, anyway.

One issue I noticed: the font size for each icon is... different.

i like the first and thrid one imo

hey, they've influenced my ship style very heavily. makes sense ;)
