Third War of Armageddon. 998.M41
The Tempest Angels committed the Fifth Company and two terminator squads from the First, supported by enough land raiders and rhinos to carry every marine. The Fifth Company were deployed to the mountains initially, performing strikes against tides of orks that intended to fall upon the cities below, whilst the task force from the First- lead by a Veteran Sergeant reinforced Hive Volcanus, venturing out to perform surgical strikes to sever key links in the green tide.
Later, the First Company task force and half of the Fifth Company lent aid to the Salamander's very successful series of assaults along the Hemlock river.
