Editing 1st Mars Expeditionary Force (section)

===Operation Tusk, Hive Manufactorum XII, Segmentum Pacificus, 912.M41===
A group of the 1st MEF were diverted from the main regiment to assist in the retaking of a factory world and came across an Armored Fist company of Armageddon Steel Legion troops and were awed by the aggressive tenacity the troops showed when they dismounted their Chimeras and fought off the Tau forces that were holed up inside the Manufactorum. They aided the Armageddon troops in the retaking of the world and collected some Chimeras and troops from that revered Legion.
