This refers to a specific plastic model kit produced by Games Workshop for the Warhammer: The Horus Heresy tabletop wargame. It represents a squad of Space Marines equipped with Mark III ‘Iron’ pattern power armor, a suit of armor prevalent during the early stages of the Horus Heresy civil war in the 31st millennium. The ‘L/A’ designation indicates that it is a Legiones Astartes unit, meaning it belongs to one of the original Space Marine Legions.
The significance lies in its ability to represent a core infantry unit within a Horus Heresy army. The Mark III armor provides a visually distinct aesthetic that evokes the brutal, grinding warfare of the era. Its availability allows players to field historically accurate and thematic forces, contributing to the immersive experience of recreating battles from the Horus Heresy narrative. Furthermore, it offers a relatively inexpensive entry point for new players to build a sizable and effective force.
