1. Hirelings, or mercenaries, hail from a variety of military backgrounds beyond just Special Forces. They may have served in the infantry, air force, or marines, among others, and possess a range of skills and experiences.2. While individuals with Special Forces backgrounds are highly sought after in the mercenary world, not all hirelings are former Special Operations soldiers. Their salaries vary based on the risk involved in the assignment, their military branch, and their point of origin.3. The requirements for joining a mercenary group are generally less stringent, encompassing civilians, ex-military personnel, and even adventurers. As long as they pass the entrance criteria, they can be admitted.4. Certain renowned mercenary units, such as the French Foreign Legion, do not inquire about their members' prior backgrounds. As long as candidates pass the entry examination, they can receive training and become part of the legion. The legion is said to favor Chinese recruits due to their obedience and resilience.5. In the United States, private security firms often act as intermediaries for hiring mercenaries rather than the government directly. These companies, founded by individuals with military backgrounds, may be involved in tasks that the U.S. government or military prefer to keep at a distance to mitigate risks and provide deniability when necessary.6. Security firms in the U.S. typically recruit personnel for specific missions to ensure a high standard of quality. These companies may participate in operations that the U.S. government or military cannot address directly.7. In Afghanistan, Chechnya, and other conflict zones, motivations for joining the ranks of hirelings extend beyond financial gain to include religious extremists who fight for their faith. These individuals may have less combat experience and often require training to enhance their abilities.
