The Battle of Lomatin IV was a battle between two states signatory to the Treaty of Kammzdast in 2351 BCE (reference stardate -43/51).

The battle took place on the planet Lomatin IV, with Orion slave soldiers fighting on both sides, on ground, in the air and in space. This was in contravention of the Treaty of Kammzdast, which specified that proxy warfare using Orions could only take place on Botchok, not offworld. The governments of Botchok protested and the master races were censured under the Treaty. However, the practice would continue, albeit more discreetly.
