Continuity mistake: When Reade is in Weller's office, his face is still pretty bruised, especially around his left eye and cheek, from the drug dealers beating him. When he's talking to Zapata outside of Weller's office, his face isn't as bruised up.
Continuity mistake: The team is assaulting the warehouse. The sights on one team member's gun changes 3 times. He starts with a scope, then a quick shot with no/iron sights (and a foregrip has been placed over his rails at the front) and then a reflex sight (a red dot).
