Terminator 3: Rise of the Machines

Just as they were leaving the Computer Center, they looked back in time to see
the main elevator doors opening. A group of eight or ten technicians sprang up
from behind consoles meaning to scramble aboard the elevator and get away.

But a T-1 robot, massive on its twin treads, its red optical sensors in the tiny
cranial case ominous, its bulk almost completely filling the elevator car,
immediately opened fire with its twin chainguns. The depleted uranium slugs
tore into the people, ripping their bodies apart, blood and shattered bones flying
outward like geysers.

Terminator stepped around the corner and had started down the corridor, his
weapons at the ready.

Connor and Kate half carried, half dragged the general out of the Computer
Center, moving as quickly as they could.

Kate’s heart pounded nearly out of her chest as they held up at a corner.
Terminator took a quick look, then stepped out across the empty corridor.
“What was that?” Kate asked.

Terminator glanced back at her. “A T-1, first generation terminator. Primitive
targeting system, heat and motion sensitive.”
