<qa>  What is the goal of the study?In this study, the investigators will conduct operational research with the Royal Cambodian Armed Forces RCAF and National Malaria Center CNM to quantify the relative effectiveness of the two major interventional approaches - monthly malaria prophylaxis MMP or focused screening and treatment FSAT - in a head to-head comparison. In addition, the investigators will quantify the relative contribution of a recently advocated vector intervention for military personnel - the insecticide treated uniform ITU - in addition to other vector control measures currently employed by the RCAF. The investigators will employ the same permethrin insecticide self-application kits currently used by the US military. The investigators will estimate the cost effectiveness of each approach and attempt to define the best way forward for malaria elimination efforts in a critically important malaria reservoir in military population and their dependents who reside on the Thai-Cambodian border. The aim of the study is not only to conduct research to better define the best way forward in malaria elimination efforts in the high risk military populations, but to also build capacity within the RCAF to support and lead future elimination efforts in the most difficult-to-reach mobile populations.
