Pre-frame, objectives and orders are received from the Admin CM and CIC respectively, and are sent out to all squadron members. Squadron members are expected to show up having read through the orders.
I show up at T-30 and begin any coordination necessary with adjacent/supporting units. Our squad SOP is for everyone to be in the tower NLT T-15. Mission brief begins at T-10 and usually lasts 5 minutes or so. The brieft includes aircraft, skin, load-out, takeoff direction, flight assignments, formations for climb and en route, and any mission specific information. The last 5 minutes before we roll is for anyone that needs to hit the head or whatever.
During the mission, we usually have around 8 or so, so we break into two flights of four. Each flight is assigned a color, and each pilot a number. We maintain section integrity (two flights) up to, including, and ideally, after first contact. Section lead is the mission commander for the frame--in charge of leading and directing the entire squad. Flight leads are in charge of their respective flight.
