In a statement, the Pentagon said, "We take matters like these very seriously and are reviewing the situation to determine if any additional training or guidance is required, and if any additional policy must be developed to ensure the continued safety of DOD personnel at home and abroad." Colonel Robert Manning said during a news briefing today that to his knowledge, no US bases had been compromised by Strava's Heat Map.
