Senior trooper
Open-knowledge reference entry

Senior trooper is a rank used by several state police agencies within the United States and in some world militaries.
It is the third class in the progressive series of state trooper ranks. It is a step below master trooper, yet above trooper first class. For some agencies, the insignia for this position consists of a gold colored 'ST' collar pin worn on the wearer's right lapel while others bear a 'senior trooper' plate that is located below their nametag. The title of address is trooper or senior trooper.
Responsibilities

Senior troopers also provide mentoring, guidance, and training to newly assigned troopers. They have jurisdiction in all parts of the State or Commonwealth they serve and carry a weapon.
Requirements
Senior troopers are required to be knowledgeable on criminal and traffic laws, skilled in the use of firearms and operation of an issued vehicle.
Career progression

Begin with the source’s own compact description: “Senior trooper” is open-knowledge reference entry. The dossier treats that line as a proposition to test through Senior, trooper and Open-knowledge, not as a finished interpretation.
Why this record matters
The phrase “open-knowledge reference entry” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Jan 21, 2026. The linked authority identifier is Q17126749. None of the 0 selected statements returned an explicit reference.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
