Contingent

(adj.) Dependent on or conditioned by something else; (n.) a representative group or detachment drawn from a larger body.

From Latin *contingere* (to touch on all sides, to befall), from *con-* (together) + *tangere* (to touch).

"Major Abhilasha Barak became the first Indian woman officer to lead an Army Aviation Corps contingent on a UN peacekeeping deployment, signalling a contingent shift in India's gender-integrated combat support roles."
