What role does the Sergeant-at-Arms play within a motorcycle club?

The Sergeant-at-Arms is primarily responsible for club security within a motorcycle club. This position involves maintaining order during meetings and events, ensuring the safety of club members, and potentially protecting the club's territory. The Sergeant-at-Arms plays a crucial role in upholding the club's rules and discipline, often handling confrontations or issues that may arise between members or with outside groups. Their authority in matters of security and enforcement makes them a key figure in maintaining the integrity and reputation of the club.

The other roles mentioned in the options, such as head of recruitment, leading social events, and managing inventory and supplies, do not align with the traditional responsibilities of a Sergeant-at-Arms. These roles typically belong to other positions within the club, each with distinct duties that contribute to the overall functioning and atmosphere of the motorcycle club.
