Shirreff is an Advisory Board member of the non-for profit security organisation Genderforce, aiming to fight and prevent acts of
Sexual and Gender Based Violence in conflict and post-conflict situations. He is a founding partner of Strategia Worldwide, a risk management consultancy founded in 2016. In 2016, Shirreff published a book entitled
2017: War with Russia: An Urgent Warning from Senior Military Command. The part-fictional book suggests that Russia could easily invade the Baltic States, that war between Russia and NATO would be possible, and implies strongly that Shirreff finds military high command and government incapable of creating a suitable response. It also alleges that former Secretary of State for Defence,
Philip Hammond, tried to court-martial him when he spoke up on British defence cuts. Shirreff's commentaries on foreign militaries, such as his assessment on the strategic weaknesses of
Russia's armed forces, have been distributed by news agencies such as
Times Radio. ==References==
