The Mobility Denial System is an oil-slick-in-a-can, a combination of "Drilling Mud Additive, Flocculent and water" that renders surfaces as slippery as wet ice. Lots of tasty acronyms and buzzwords on the sell page, including "Anti-Traction Material (ATM)" and "Non-Lethal Slippery Foam."
Once applied, the material will degrade or impair the adversary's ability to move. For Interior applications it can be applied to flat, smooth, non-porous surfaces such as linoleum, tile, wood floors or staircases. Exterior applications include sloped, rough, porous surfaces such as concrete, asphalt, and grassy areas.
