Uncertainty prevails over US cyber strategy shift towards ‘persistent engagement' 23 December 2020 by Neil Ashdown United States Cyber Command deployed a team to Estonia in November 2020 as part of a new strategy that emphasises operating outside US networks. The mission, lasting from 23 September to 6 November and coinciding with the US presidential election, was reported by The New York Times on 3 December. The newspaper reported Brigadier General William J Hartman, commander of the Cyber National Mission Force, as saying that the ‘hunt forward’ mission allowed Cyber Command “to broadly observe Russian techniques in Estonia and compare them with Moscow’s tactics used in the United States”.
