The satellite communication (satcom) operating in X-band frequencies has the potential to enhance communication capabilities of Malaysian Armed Forces (MAF) and the Malaysian National Security Council (NSC). The satcom can be deployed during catastrophic instances, crisis incidences and certainly for the use of military operations. The satcom can facilitate the delivery of critical high-speed data, voice and video services between military bases, headquarters and also military detachments. The paper highlights the predicted fade margin requirements by the Malaysian Military satellite communication in order to accomplish specific operational quality of services (QoS). This is of utmost importance considering that both the uplink and the downlink will be facing severe rain attenuation due to copious heavy rainfall events, typically endured by tropical region countries. A prediction technique, recommendation ITU-R P.618-12 with value proposed by ITU-R P.637-6 had been employed in order to generate the desired results. Local data acquired from the Department of Irrigation and Drainage Malaysia had also been utilized in the generation of the fade margin estimations. The findings from the studies can offer insight of how to ensure/enhance the satellite communication links reliability.
