Ukrainian Defense Minister Stepan Poltorak expects a change in the organizational structure and functional responsibilities of the ministry's personnel.

"This won't be a mechanical reduction in the personnel, although the number of officers will be reduced by 200 men, and the number of departments and divisions will be halved. The ministry's entire personnel will undergo re-assessment," he said at a Cabinet meeting on Wednesday.

According to him, all servicemen at the ministry will have to pass lie detector tests, and their education and experience background will be taken into consideration.

He also announced change in functional responsibilities.

"I plan to transfer the most important functions to deputies the heads of departments, while liability for decision-making by the heads of departments and all civil servants will be stepped up," Poltorak said.

He expects the measures will help to make the system more efficient.
