M40M43

M40M43 is a dual-caliber modular combat platform conceived in a near-future fictional setting. The name combines the earlier M40 and M43 lineages into a single chassis, intended to provide flexible firepower and rapid mission adaptation. In-universe, it is produced by a consortium of defense firms and designed for ease of field upgrade.

Design and capabilities: The platform is built around a modular hull that can be configured with either a stabilized 40 mm automatic grenade launcher module or a 43 mm multipurpose launcher module, or both in a two-module arrangement. It features autonomous target acquisition, a compact electro-optical sensor suite, and digital battle management integration for networked operations. Armor is light-to-medium, with optional applique kits, and the vehicle can be airlifted or transported by standard military transport.

Variants: M40M43-A is optimized for reconnaissance and fire support, emphasizing sensor payload and stealth. M40M43-B focuses on crewed transport with heavier survivability and a reduced sensor suite. A command-and-control variant exists with extended communications and data-link capabilities.

Operational history: Within the narrative universe, the M40M43 entered mass production in the late 21st century and saw service with several allied forces in urban and desert theaters. It is cited for versatility in modular loadouts and ease of maintenance but remains a subject of debate for its ammunition logistics and cost.
