Qwuedeviv don't usually have helmets on a good majority of the time, but their uniforms do possess one similar to that of the Qwuedeviv on the far left but in the color of their uniform.
These are the outfits of the actual invasion force soldiers--not scout crews. Scout crews wear 'invader uniforms.' Their appearances are pretty straight forward, but you're welcome to ask questions.

*Boot and glove pawprint tred color varies depending on what division they are in.
*Privates that are above the base rank as well as elites obtain stripes over the shoulders of their uniforms.

Also I gave these guys names. They're just background characters--more backgroundy than my usual 'background' characters--but I liked them. =p
From left to right:

Ou'jiierr (Twisted Krill Grill) "Krill"
Tis a pilot. Namely the one who dropped Crew 52 off originally. It's kind of a sardonic Qwuedeviv who gets a kick out of holding back most of the details. It isn't very fond of the other divisions of the army, deaming them bossy and overrated.

Drenn (Dust)
From the Army division, Dust is one of many. There is nothing that particularly stands out about the Qwuedeviv. Other Qwuedeviv have claimed its tail is 'cute' though before. Dust isn't sure how it feels about these comments.

Omm (Marbled Mud) "Mud"
A Qwuedeviv in the rather small Navy. It has no fear of water. It is fairly peaceful and rarely sees any action. Enjoys hanging out with most any other Qwuedeviv from whatever division.
