Yes and no. It may not have been practical to destroy every single piece of equipment during a rapid withdrawal, but it was absolutely possible to render the majority of it inoperable. Militaries routinely conduct denial procedures when abandoning hardware. For example, disabling a Humvee permanently is not complicated removing or destroying the engine control module (ECM), damaging the transmission, cracking the engine block, cutting wiring harnesses, or stripping critical components can make restoration extremely difficult without an established supply chain.
