(NBC News) - Rarely is a wheelchair this tricked-out and durable enough to plow down any terrain it comes across, just like the tank it was modeled after.
The "Tankchair," created by combat veteran Brad Soden, includes heavy-duty treads that can glide across just about anything, from rugged hillsides to sandy beaches to snowy embankments.
Soden, who never studied engineering or even went to college, created the Tankchair as a way to help his partially paralyzed wife, Liz, who said it's impossible to drive the chair without drawing attention.
