The defense budgets of the Member States of the European Union are rising due to the current economic situation and change in the level of security. The goal of approaching two percent of gross domestic product will probably be reached within one decade. However, the positive trend in the development of the defense budget w ill not allow small states to acquire the exact numbers of military techniques in the numbers that imply a continuous increase the capacity of national armies. Pooling and sharing is one of the approaches that will allow the required capabilities of national armies to benefit the European Union, or the North Atlantic Alliance. Deepening co-operation in the field of acquisitions will put pressure on coordination of activities, alignment of legislation and, above all, overcoming national and common. Obviously, given the current combat experience, the issue of armed forces has already been partly solved and pooling & sharing implementation is a political issue.
