Headquarters reside in Bulgaria, and for the purpose of promotion of the sport internationally the organization offers a ruleset which regulates the design and management of competitions.

Competitions consist of several stages, and the competitors have to move between different parts of the stage under a time limitation, quickly assume stable or unstable shooting positions, and use theoretical background to successfully make precise long range shots.

The main idea behind T-Class is to create realistic long range shooting competitions which are open to civilian sport shooters, police and military forces.

Points are awarded by measuring each target in every exercise in milliradians (mrad) which takes into account its size and distance.

The calculated sum in percentage from all the three modules finally assembles the match ranking and demonstrates the winner.
