Special Operations Engineer Regiment
The Special Operations Engineer Regiment (SOER) provides Special Forces Group with leading-edge mobility, survivability and specialist counter-CBRNE (chemical, biological, radiological, nuclear or explosive) capabilities in support of Australia's national interest.
SOER combat engineers are highly trained to work alongside other special forces on a range of contingencies, both domestically and on operations overseas.
SOER's motto is 'Inter Hastas et Hostes', which is Latin for 'Between spears and enemies'. This signifies the traditional sapper role and enduring unit requirement to operate in the dangerous space between enemy threat forces and own troops in order to ensure mission success.
