The walker that Rick encounters in the tank at the end of the episode was played by Sam Witwer. The original intention was to have a web based spinoff showing how Atlanta fell and how Witwer's character died in the tank. This never materialized since Frank Darabont was let go from the show.
Rick tells the deputy that he hopes his sidearm is loaded and the safety is off. The deputy then racks the slide, loading a round in the chamber and flips his thumb and a click is heard as he flips off the safety. Two problems: Police officers always go out in the field with their sidearm loaded and the gun was a Glock, there is no external safety on the Glock. Also, spike strips do not work as shown. They leave hollow tubes in the car's tires that deflate them slowly so that the car slows and becomes more difficult to maneuver.

Dwayne: Daddy can I learn to shoot? I'm old enough.
Morgan: Hell yes you're gonna learn. We gotta do it carefully, teach you to respect the weapon.
Rick: That's right. It's not a toy. You pull the trigger, you have to mean it. Always remember that, Dwayne.
Rick: (to Shane) That vase - that's something special. 'Fess up. You steal that from your Grandma Jean's house? I hope you left her that spoon collection.
Rick: (to the legless walker) I'm sorry this happened to you.
Unknown Speaker: Hey you! Dumb***. Yeah, you in the tank. You cozy in there?

No animatronics were used to create the "Legless Walker". It took a three hour process of adding prosthetics, makeup and CGI blue screenpieces to actress Melissa Cowan to achieve the desired look.
The "Legless Walker" that Rick encounters is given a back story via Webisodes on the AMC website. Her name was Hannah and was trying to get her children to a safe spot when she got killed and torn in half by walkers.
This episode has the same title as the first The Walking Dead trade paperback.

When Rick leaves the hospital he passes an abandoned air cavalry helicopter. The logo on the front is the crossed swords with the number 7 in the middle, which would make it the 7th Air Cavalry unit. The Seventh Cavalry was George A. Custer's unit that was massacred at the Little Big Horn, and that numbered unit was retired from service.
