The OPMOD Battle Mug is a "tactical" mug, "machined out of a 13.5-pound solid block of aluminum". The mug features a crenelated bezel (presumably for inflicting damage by striking), as well as mil-spec picatinny rails for mounting weapon accessories. Some of the employees at OpticsPlanet made a Youtube video with a wide variety of red dot sights, magnifiers, laser sights, a bipod, several flashlights and other accessories mounted to it.

According to the OpticsPlanet blog, the fully loaded version of the OPMOD Battle Mug features over $5000 in equipment attached to the $250 mug.

The OPMOD Battle Mug video first started to go viral on Jan 26, 2012 when it was posted to fark.com. Activity stayed relatively dormant until Feb 24th, when it was posted to Geekologie, Gizmodo and a handful of other sites. Interest in the OPMOD Battle Mug continued to build until on March 1st the OPMOD Battle Mug was featured on the front page of "Science & Technology" at Fox News.

A response to the original OPMOD Battle Mug video was posted by TheTruthAboutGuns.com, featuring several of the writers for the blog shooting the OPMOD Battle Mug with various caliber firearms, putting it through several tannerite explosions, dragging it from a truck, and finally running it over with a bulldozer before the structural integrity of the OPMOD Battle Mug gave way.
