Camp Nama is a secret military base, where soldiers were trained to be part of a special group known as Task Force 121. This group was responsible for carrying out missions in the wars in Iraq and Afghanistan.
Now, imagine you are playing a game with your friends, and you need to have a very special team to complete your mission. This team will have some members who are really good at shooting their toy guns, some who are really fast at running, and some who are very clever in making plans.
That is exactly what Camp Nama did, they trained soldiers to be part of this special team (Task Force 121) who were really good at different skills like shooting, running, and making plans.
However, some soldiers acted badly and did some things that were against the rules. Just like how in the game, if someone cheats, then the game is not fun anymore. The military found out about the bad things that were happening in Camp Nama and made sure that things were better for the soldiers there.
