Any suggestion for mercenaries logo?

[Yak]

I'd try to answer a few questions about the group itself, I find it's a lot easier thinking about symbology for that sort of thing once the background is fleshed out a bit.

Where do they come from/where they're based?
Lawful/Unlawful/Quasi?
Is the group old/new, rich/poor, sophisticated/brutish, honorable/backstabbing?
Are they related to a vanilla faction? (might be able to incorporate elements/ideas from an existing logo)

Even the group's name/tag can be a really good starting point to spark off an idea.

For example, a group of ex-Lib Navy pilots might have quite a swish-looking "military" logo,maybe with some elements of Liberty's House flag included.

On the other hand a bunch of ex-convicts might go for something a bit more grungy, maybe some almost "piratey" looking symbology.

Err... hope that was sort of some help
