In many African countries, National Police Reservists (NPRs) play a critical role in enhancing community security, particularly in remote and conflict-prone regions where formal law enforcement agencies have limited presence. In Turkana County, Kenya, NPRs are instrumental in supplementing the Kenya Police Service to maintain peace and order. However, despite their indispensable contribution, NPRs face numerous forms of vulnerability that significantly affect their safety, morale, and effectiveness. This study examined the nature of vulnerability experienced by National Police Reservists in Turkana County. The research was anchored on Stark Rodney’s Vulnerability Theory (1987), which explains how individuals or groups become more exposed to threats due to structural, institutional, and community-based factors. A descriptive research design was employed, covering all sub-counties in Turkana. The study population comprised 875 individuals, including NPRs, officers from the County Commissioner’s office, village managers, and Members of the County Assembly. A sample size of 109 respondents was obtained using stratified random sampling. Data were collected through questionnaires and key informant interviews. NPRs and village managers participated in interviews, while officers and MCAs filled out structured questionnaires. A pilot study was conducted in West Pokot County to ensure validity and reliability of the instruments, with reliability confirmed using Cronbach’s alpha. Findings revealed that NPRs in Turkana County experience multiple layers of vulnerability, primarily emanating from civilian threats, inter-communal hostilities, and inadequate institutional support. A significant proportion of NPRs reported being threatened, intimidated, or assaulted by civilians from rival communities, often leading to physical harm and psychological trauma. Community-level vulnerability was also found to be reinforced by negative perceptions towards NPRs, including mistrust and discrimination. At the state level, NPRs face challenges such as insufficient logistical support, inadequate protective gear, and lack of structured welfare systems. Policy gaps and weak legal protection further exacerbate their exposure to risk. These vulnerabilities not only compromise the personal security of NPRs but also undermine their operational capacity in maintaining peace and responding effectively to security incidents. The study concludes that vulnerability among NPRs is a complex, multi-dimensional issue that stems from community dynamics, weak state structures, and policy neglect. It recommends that the government enhance the legal and institutional framework governing NPR operations, provide adequate protective resources, and improve welfare systems to strengthen their resilience and operational effectiveness
