Multi-domain operations cover integrated operation of cyberspace, space (meaning satellite operations, from the Army's perspective), land, maritime, and air. A multi-domain task force was stood up in 2018 in I Corps for the Pacific, built around 17th Field Artillery Brigade. MDO in the Pacific has to involve maritime operations; MDO is planned for EUCOM in 2020. Multi-domain battalions, first stood up in 2019, comprise a single unit for air, land, space, and cyber domains to ensure integration of cyber/EW, space, and information operations in more levels of command.
