The comic is called Romantically Apocalyptic and is illustrated by Vitaly S Alexius.
From the Info page
I am the captain.
The year is 20__ something something.
I stopped counting a while ago, and therefore not sure what day it is.
Humanity is virtually wiped out in a nuclear holocaust.
Me and my last squad: pilot, sniper and engineer, live in the wasteland ruins of tomorrow.
This is my story.
I am captain.
It’s got apocalypse, funny hats, gas masks, inanity, skeletons and a fellow that goes by Captain.
I enjoyed the pictures, like any simple-minded boob, and the Captain is just my sort.
The site indicates that there is some kind of live action series in the works as well. The story is worth a look in its current form, either way.
