Jin military service represents a pivotal chapter in Korean history, uniting elite warriors under a centralized banner to defend the realm. This system strengthened royal authority while shaping regional power dynamics through carefully structured recruitment and governance.
Modern analyses examine how these arrangements influenced taxation, land control, and frontier security. Understanding the Jin military service framework reveals how medieval states balanced local autonomy with imperial demands.

| 1100s–1200s | Gun (County Militia) | Rotational service, transport convoys | Tax remissions for active duty families |
| 1200s–1300s | BuSuppress banditry, patrol trade routes | Customs shares redirected to central treasury | |
| Peak centralization | Royal Guards | Court security, ceremonial parades | Direct stipend from monopoly markets |
