S.S.D.D. is the first level of Call Of Duty: Modern Warfare 2.
The mission starts the player controlling Pvt. Joseph Allen. Your first task is to “train” the local Militia how to shoot correctly - this serves as a basic tutorial of sorts. Once you have “trained” the militia you will see a new checkpoint appear which guides you to The Pit.
The only piece of Intel in this level is found shortly after training the Militia and before running the Pit. Whilst making your way towards the Pit entrance look to your left and you will notice a large white guard tower with a table at it's base, on this table is the first piece of Intel.
