The purpose of this study was to examine the influence of physical material distribution on service delivery at the British Army Training Unit, Nanyuki, Kenya. This study was pegged on the human systems dynamics and the institutional theory. A descriptive research design was adopted to analyze the effect of materials management on service delivery. The target population was 535, from which a sample of 229 respondents was used to obtain information. A stratified random sampling technique was used to ensure that there are no biases in the selection of the respondents. The respondents were divided into two strata; the industrial and non-industrial employees. Data was collected using a questionnaire, which contained open and closed-ended questions. The validity and reliability of the questionnaire was tested using content validity and Cronbach’s Alpha, respectively. A pilot study was undertaken at the Kahawa Barracks. The data collected was analyzed using SPSS software. Descriptive statistics enabled the researcher to present data in a meaningful way, while inferential statistics helped to deduce meaning to the findings. A regression analysis was conducted to test the hypothesis presented in the study. Presentation of the findings was done with tables and graphs. On the effect of physical material distribution, the study found out that there is a strong transportation system in the organization, however; no regulations had been put in place to select the transportation modes also the study uncovered that the organization had made sufficient investments for warehousing infrastructure. In addition, physical material distribution was found to have a positive correlation with service delivery (r= 0.319; p= 0.000). There was a demonstration that a statistically significant relationship exists between physical material distribution and service delivery at BATUK. The study recommended that a similar study should be conducted in other organizations in the public and private sectors in Kenya.
