Which Book Cover Works?

I need your help in selecting the book cover for The Last Republic

Ok, guys. I finally got some images back from the artist. What cover do you like? Blue Beehive, Blue Viper, White Beehive or White Viper. Note that BunkerBranding will make a unit patch for this fictional Deseret squadron and sell it on BunkerBranding.com, or give it away with signed copies of the book if you buy it on BunkerBranding. I'm thinking each book in the series will have a new cover patch. Nauvoo Regiment (who are kind of like VDV/Rangers) ... 6th Urban Warfare Division... 5th Coastal Infantry (sort of like Deseret's Marines)

So here are the choices:

Blue Beehive

White Beehive

Blue Viper

White Viper
