Trooper first class

Trooper first class is a rank used by several state police agencies within the United States and in some world militaries.

The insignia for this rank consists of a gold colored 'TFC' collar pin worn on the wearer's right lapel.

However, the Illinois State Police collar insignia is one silver chevron.

Troopers who complete five (5) years of satisfactory or exceptional service are promoted to the rank of trooper first class.

After attaining this rank, the trooper first becomes eligible to test for a supervisory position as a sergeant.
