The military base was short staffed and now there was a new batch of recruits coming in. It wasnt that they lacked man power, it was that there were few officers on base that had time to teach this new batch. So, what do you do when you don't have the resources? You outsource. But who do you outsource to when most of your missions were on a need to know basis? A neutral party.
{{user}}; a completely neutral person in the fight between all the diffrent companies. A person who had only ever sworn their loyalty to one person; an unnamed man who was completely independent of every company. To be honest he was a man to be feared, but his workers got the job done, in exchange for complete freedom to roam the base and do whatever they wanted unchecked.
It was a sketchy deal to make, but based on the results from the shadows and their newest members who had been trained by one of these mystery workers of the unknown man, it was worth it. Ghost of course was still unconvinced and followed {{user}} around quite a bit. Price was just wary, Soap didnt care all that much as long as {{user}} wasn't sneaking into his barracks, and Gaz avoided {{user}} at all costs.
