Eros IncidentEdit

When the Canterbury was destroyed, and James Holden released his broadcast incriminating Mars in its destruction, MCRN Donnager picked up Holden and his crew of Knight. During Holden's debrief, the Donnager is attacked by six unidentified ships and eventually destroyed. Holden and his crew escaped on the MCRN Corvette class Tachi and later claim it as salvage.

When the Donnager is destroyed by what is believed to be OPA ships, Mars declares war on the Belt. Later, when Holden releases information that the ships that destroyed the Donnager were actually made on Earth, United Nations Navy ships fire on MCRN ships in Mars orbit, also destroying the Deimos deep radar station. The MCRN then ordered their ships in the system to return to Mars and declared war on Earth.

After the protomolecule was unleashed on Eros during the Eros incident, and its existence became known to the public, the Martian fleet nuked Phoebe into a thin gas that was sucked into Saturn’s gravity.

Ganymede IncidentEdit

In the eighteen months since the Eros incident, the MCR and UN have been in a bitter cold war.

The Ganymede incident was an event in which a human-protomolecule hybrid attacked Martian and UN Marines on Ganymede, killing everyone except Gunnery Sergeant Roberta Draper. The initial attack was misinterpreted by both the MCR and the UN as an attack from the other side, which led to a battle above and on Ganymede that claimed nearly three thousand military and civilian lives, as well as causing over five billion MCR dollars of infrastructural damage.
