Supply chain agility is very essential to supply combat ration for any army unit. As it is knownrncombat ration is required when there is a field mission including war. Nowadays it is difficult tornobtain combat ration from the supply market when it is needed urgently. Because of this thernstudy aimed to investigate the gap of combat ration supply chain agility in response to urgentrnmilitary mission the case of Ethiopian defense logistics. Combat ration is arnfundamental thing for successful accomplishment of military mission on war front. The studyrnemployed descriptive research design. The reason the researcher used descriptive researchrndesign was to identify and describe the gap of supply chain responsiveness for uncertain demandrnof combat ration for urgent military mission. The researcher also used descriptive researchrnstrategy to determine the relationship between agile combat ration supply for urgent military missionrnand the five supply chain agility dimensions stated in the study as dependent and independentrnvariables. Qualitative and quantitative data has been collected and analyzed using frequencyrnand percentage. The population of the study was selected by non-random data samplingrnmethod/purposive data sampling from the supply chain members of combat ration. The samplernsize was 106. From this sample size 5 top managers gave interview additionally. All respondentsrnreturned their questionnaire. The study is conducted on the following specific conceptual framernwork of supply chain agility dimensions alertness, accessibility, decisiveness, swiftness andrnflexibility. The research found that combat ration supply chain is not alert enough to respondrnurgent demand, combat ration supply chain information is partially accessible, and combatrnration supply chain is not flexibility to respond the demand as per the military mission requires.rnThe supply chain is not agile enough to respond urgent requirement of combat ration duringrnurgent military mission. The proposed recommendation for the gap identified in the study is: tornestablish an agile supply chain of combat ration by multiple sourcing, making a strongrnrelationship with existing supply chain members, advancement of supply chain informationrncommunication technology and flexibility of using variety of combat ration through advancedrnmanufacturing technology.
