Black Mesa Tactical Operations Vehicle
HEAVILY modified 1987 GMC S-15 Pickup (Same as a Chevy S-10). Only original parts are the frame, some of the cab, the rear axle, the front differential & control arms. Everything else has been changed.
I've had this truck quite longer than the Aperture laboratories Commodity Location Alteration Vehicle, but just noticed I have NO pictures of it on my dA! So here she is.
