It isn't just us. There's always an operational planning process that goes on. It's the same for the combat arms. The army, navy, and air force go through the same planning process. The support logistics community goes through the same process. These missions are all analyzed by the senior staff, and we add our input on whatever we're asked to do. Others make the decisions as to whether we're going or not. They don't take these decisions lightly. All of the input is factored in.
We have both been in the position of providing operational advice to the senior staff from a medical perspective, and we give them exactly what we can or can't do at that particular moment.
