The exact role of the gendarmerie has been historically difficult to ascertain, with several changes and developments since the fall of communism.

Prior to the abandonment of conscription in 2009, the ZW was primarily concerned with the conscription efforts of the Polish Armed Forces and chasing down avoiders, however the unit returned to traditional military policing after this with a confusing hiatus of their public role and deployment for 10 years with ad-hoc deployment at the government's will.

In further confusion, in 2021 the Gendarmerie was demoted from a full service branch of the Polish Armed Forces, instead being classified as an "other" unit, alongside the Inspectorate of Armed Forces Support (logistics unit), the Warsaw Garrison (various representational and ceremonial duties in the capital), as well as the Operational Command and General Staff which are the main decisional organs in the chain of command.

Among other notable role changes and developments in the last two years, the ZW has overtaken all duties on patrolling the highways and national roads to inspect the goods of large trucks and their roadworthiness, and for the first time arrest powers were extended to the ZW when dealing with truck drivers who carry unregistered arms, drugs or illegal immigrants which fall out of the jurisdiction zones of the border force.

In the past, ZW units have been regularly deployed for this purpose to search for deserters and conscription-avoiders and much experience remains in this area.

Notably however, they have been excluded from protests (from which they are constitutionally banned) and VIP/government protection (unlike other Gendarmerie forces in Spain and France, however, in Poland this role is undertaken by the SOP).
