20 Things You Somehow Missed In Toy Story
7. Sid Is (Probably) A Military Brat
We know that Sid is a deeply troubled boy, but there are several suggestions that he might also be a military brat and have received some undue influence from his mother or father's time in service.
For starters, when Woody hides in the milk crate in Sid's room, inside is a manual called "TM 31-210: Improvised Interrogation Techniques," which we can safely assume Sid has studied extensively given that we see him both interrogating and torturing toys throughout the film.
TM 31-210 is actually a real military manual, though in reality it's a handbook for weapons and explosives rather than interrogation.
The other big indication that Sid is being raised in a military household is the fact that his dog is named "Scud," most likely a reference to the scud missiles which were famously used by Iraq during the Gulf War.
Given that Toy Story was released just a few years after the Gulf War ended, it's a fair assumption that at least one of Sid's parents may have served.
