The Arms draw permanent members from Combine Central for recruitment. The Arms themselves are self-contained playerbases who perform the wide range of duties.
Arms as Organisational ResourcesEdit
Each Arm has clearly defined goals and duties stated on their respective pages. The Scholarly Arm is administrative and media staff and the Militant Arm is a standing military and combat operations. Members placed in the Arms have specific duties to fulfill. Both Arms have completely different ranking systems and no player is allowed to be in both Arms simultaneously.
The Combine was originally formed with two Arms, before the need for better organisation arose.
