The Operation Instruction(作戦指示書Sakusen shiji-sho) is a file that can be found in the Saint Michael Clock Tower in Resident Evil 3: Nemesis. The overall context of the file is an order from Umbrella to a unit designated "Echo Team". It is this file which confirms that what Carlos Oliveira was saying was the truth - the U.B.C.S. were given orders to assist in civilian evacuation. It also makes reference to the clock tower being intended as a waypoint for evacuation, as was suggested by the Delta Platoon survivors earlier in the game.
