When this squad was formed, it came directly under the control of the Director of Intelligence or his deputy and under no other authority.
Sometimes the squad was strengthened by members of the Intelligence staff, the Active Service Unit, munition workers and members of the Dublin Brigade, as occasion demanded; Tipperary Flying Column men, Dan Breen, Séamus Robinson, Seán Treacy and Seán Hogan; also Mick Brennan and Michael Prendergast Co Clare.
