JTF 2 is comprised of CF members employed in assaulter and supporter roles. All members are carefully screened for service in the unit but it is the assaulters who undergo a selection and training regime for eventual service in the fighting arm of the unit. Any Regular or Reserve Force member of the CF can apply to become a member of JTF 2 after completing 2 years of service and meeting other initial entry requirements. Members of JTF 2 are highly motivated, dedicated, mature, mentally robust and physically fit. Potential assaulters are carefully screened to ensure that they meet these criteria and are the type of team-oriented and highly skilled professional soldier, sailor or airman that can effectively function in this high stress environment. The CF's strongest asset is the people that fill its ranks across the country. Many of these service members have tried out for the JTF 2 selection process but, on average, only two in ten candidates that arrive at the unit for final selection will actually become a JTF 2 assaulter.
The standards established for selection and employment with the unit are scientifically designed and validated at the CF Dwyer Hill Training Centre in order to ensure that the members selected will be capable of accomplishing all tasks assigned to the unit. These standards are not just limited to physical abilities. High standards are also required for professionalism, integrity, psychological profile, mental aptitude, discipline, and maturity. These standards are required of all unit members, are tested regularly, and are an integral part of the JTF 2 ethos.
