Abstract : The fundamental problem is whether a serious threat to the US Army's traditional command and control exists because of proposed plans by a government employee union to organize military personnel. Several facets of the Army's personnel structure is examined, including its traditional ethnic and class composition and its career and non-career mix. The conclusion is drawn that the threat is minimal to the active Army, but serious to that 40% portion of the total force comprising the reserve components, by reason of large numbers of full time technicians holding key unit positions who are members of unions.
