Sentinel 3-R is identifiable by the "3-R" displayed prominently on its torso. This Sentinel was first seen in panel 1 on page 11 in The X-Men (vol. 1) #14.
Sentinel 3-R was the most prominently featured Sentinel in X-Men #14. Through his actions, much of these Sentinels' "thinking" was glimpsed. The desire to return to the place where it was created was so strong within Sentinel 3-R that Charles Xavier was even able to receive vague mental impulses from the robot, despite the fact that normally robots are completely imperceptible to Xavier's telepathic powers.
