"We knew everything about the location of the Estonian soldiers," Kalniņš said.
Kalniņš also said that during the drill there was positive indications over the direction the armed forces are taking and that the exercises have not revealed serious problems.
Nevertheless he indicated that the exercise serves as a reminder that the National Armed Forces have to continue with armament upgrades and infrastructure development.
