Already in 1943, in London, the Belgian State Security and the 2nd Direction (Counter Intelligence)
of the Ministry of Defence agreed to work together, once Belgium liberated,
to track down all war criminals and military collaborators.

As most military collaborators fled to Germany, it was only once the War
had ended that the real work could start.

Four Field Security Sections were raised, each consisting of one officer, five NCO's and five men.

Several Interrogation Sections were also raised, each consisting of four officers, ten NCO's and thirtynine men.

The Security Sections and the Interrogation Sections were put at the disposal of the 21st Army Group.

SHAEF also requested Belgian help, especially military with good notice of German and English,
for the 12th US Army Group.

This Belgian CI Mission, seven officers and ten men, consisted of four teams.

As most were civilians, they were assimilated to a military rank and wore specific rank insignia.

On the collars of the battledress, officers wore white embroidered Belgian lions,
NCO's light grey embroidered lions,
and coporals and privates wore blue embroidered lions.

Field officers wore a 3mm width bar under the lions, senior officers a 7mm width bar.
