The Star League developed and deployed battle armored infantry. They were used as marines aboard ships and space installations, as shock troops to clear out conventional infantry, and to some extent as an anti-mech weapon. Full SLDF Battle armor is now lostech, but all major combatants employ jump infantry. Jump infantry wear armored exoskeletons (basically the IS version of battle armor), which allows them to carry more firepower into battle than normal infantry. Jump troopers get their name from the personal jump packs the use to improve their mobility. They are invariably elite soldiers, as the equipment requires a lot of skill to use and is too expensive for general use.
