Most folks would agree that it takes just a few hours, and they would be right. In my case, it also took just a few hours though said hours were delayed by 15 or so months between the time of purchase and the removal of the box's shrink wrap.
Here of late my poor marines have been finding themselves increasingly outgunned on the table top, with only my Hellblaster squad seemingly able to hold the line effectively. That said, I only had 6 of them making the squad both over-taxed and easily eliminated. However now that I have 16 ready for battle, I'm hoping that they'll even things out a bit for me. Only time will tell though...
The Smurfs are now my only marine army with the Incandescent Coyotes (all 23 of them) currently redeploying to the Illy-Noise subsector. Their fully painted 'Woolly Bear' Razorback has taken up residence in my display cabinet, whereas the Coyotes' half-painted rhino was reprimed in anticipation of being (eventually) repainted in Ultramarine colors.
Not many of the unpainted Coyotes were retained due to all of the Space Wolf Coyote accoutrements. Like the also defunct Silver Drakes, the remnants of the Coyotes were folded into the Smurfs making it a rather large army at this point.
