Thanks, guys!
Jeff, that's probably because it is a post-apocalyptic dio.
Set loosely in the "28 Days Later"/"28 Weeks Later" universe, I occasionally call it "28 Months Later" (Buzzbomb has also used this title for a similarly themed build - & one of his builds inspired me to do this).
In a world ravaged by the Rage virus groups of survivors, called Scroungers, dig through the remnants of civilisation looking for supplies of food & materiel. Faced with isolated outbreaks of the Rage virus & roaming bands of marauders & bandits Scroungers are always well armed. This diorama shows a Scrounger reconnaissance patrol which has come upon the entrance to an old warehouse complex, where there are ample signs of a past tragedy. Still, the need for supplies demands that they investigate the site more closely.
