I run the Ghostbusters emblem - yeah, not my own, but I like it. Ran it in the first Black Ops, running it again.
I try to keep mine really simple - and if someone is curious enough "informative".
The one I really like is "Ludwig Von Mises" [I think it pops-up on ELITE too]. I don't think there's too many people that know the "Mises" economic concepts - and given the state of global-economy - with all of the central-banking intervention - I'd really like more people to at least know about Mr. Mises. It don't matter if they disagree & still love their Keynesian concepts - at least they have a chance to learn about Mises.
I have another one with a "religious" swastika & the words "Vande Mataram" - only for those few days I tend to feel a little patriotic.
My cousins and I went for individuality and creativism. We all have power ranger helmets (made with no tutorial).
I have the Red and Black ranger.
One has the green and white ranger.
One has the blue ranger.
and the only female cousin that plays has the pink ranger.
Didn't spend alot of time on it - Red Elite Skull with my Clan tag underneath it MMNS.
Murder Machine Nova Scotia.
Its simple but simple shows up better on your gun - the all red symbol looks awesome on Carbon Fiber Camo.
I have a couple of different emblems but the one I use the most is my Marine Raiders emblem (although I use a black background so the white stars can be easily seen)
No one fights alone!
Have 3 I switch from, most used is confederate flag. 2nd is a roll tide emblem, 3rd is "don't tread on me" in yellow and green.
