"The paradox of military technology states that while increased complexity in a military force results in increased capability, it also increases the likelihood that the capability will be unavailable for use because of the collapse of the complex supply chain required to maintain the capability. The implication is that complex military technologies might not be the best acquisition strategy for defence forces in the future."
