Indeed. It looks to be inspired by the RAH-66 Comanche stealth helicopter [1]. Currently operators are known to use (through Mil-COTS) the Toyota Hilux. Maybe Elon is after an influx of SOCOM/DARPA money for Tesla (increasing his association with Tony Stark in the process).

The thing I find interesting about this truck design is the angled body. It looks like it's designed for minimised radar cross section (RCS) signature, which is a military application benefit.
