In the 2024 Fallout TV series, we see that the Brotherhood of Steel’s squires are portrayed as young adults (or older teenagers). For instance, Aaron Moten, who is 35, plays the squire Maximus, and his character is actively serving alongside a Brotherhood knight in a combat situation.
This portrayal contrasts with Fallout 4, where Brotherhood squires are depicted as children in their pre-teen to early teen years and are not permitted to participate in combat.
Brotherhood squires are children serving in the Brotherhood of Steel. Technically the lowest rank one can hold in the Brotherhood, squires are not allowed to participate in combat operations. Instead, they perform errands and menial labor, occasionally participating in field training exercises.

By 2277, the East Coast chapter of the Brotherhood has adopted the rank of squire as a title for children who have been born into, or been recruited by the Brotherhood, making it the lowest rank in the chapter. These children are not permitted to take part in combat. Instead, they perform errands and menial labor for the Brotherhood's military and are provided with training and education in return. They also appear to be heavily conditioned by propaganda, with those aboard the Prydwen claiming not to fear death and possessing an almost religious devotion to the Brotherhood. Upon reaching adulthood, squires become initiates and begin active duty.
Squires are occasionally taken out as observers on a sweep and clean mission led by high-ranking members of the Brotherhood. Lancer Captain Kells bestows such a responsibility upon the Sole Survivor in the radiant quest Leading by Example. The squire that accompanies the player character does not take part in the fighting and is merely there to observe and study combat techniques.

Was the concept of squires as young adults engaging in combat introduced in the TV adaptation, or is this a detail with precedent in earlier Fallout games or other media? If the latter, in which Fallout title were squires first presented in this way within the Brotherhood of Steel's organizational structure?
