I discuss an experiment that tests the prediction of the social impact theory that immediacy matters and the claim that trust partially mediates its impact in command and control settings. Active-duty soldiers completed oral commands more quickly when collocated with an unfamiliar leader than when that leader was sheltered at a remote location. A questionnaire on trust in the leader revealed greater levels of trust in the collocated condition. The best-fit linear regression function reveals a significant positive association between self-reported levels of trust and response time. Additional regressions reveal that trust mediates the influence of immediacy on the speed with which soldiers executed direct orders. These findings support arguments against plans proposed by both the U.S. and Swedish armed forces that would extract platoon leaders from the field and replace them with remote command and control of the dismounted infantry.
