If anyone is wondering what that looks like, it happens at the end of a Triumph, where the honored general and his army* gets to parade through Rome with all the treasures, exotic animals, and captives they took on campaign. If the enemy leader or general was captured, the Triumph ends with them being ritually strangled.

*the significance of the army being in Rome is that no one was allowed to enter the city under arms. Once a soldier crossed the pomerium (city limits) they are treated as civilians in the eyes of the law.
