UEF

UEF is an acronym with multiple meanings across different domains. The most widely recognized usage in popular culture is United Earth Federation, a fictional interstellar government or faction used in space opera and strategy games.

In the real-time strategy game Supreme Commander and its Forged Alliance expansion, the United Earth Federation is one of the three main factions, alongside the Cybran Nation and the Aeon Illuminate. It represents a centralized human civilization formed from Earth’s unified government. The UEF faction is typically portrayed as emphasizing durable, conventional military hardware, solid production capabilities, and reliable logistics. Players often rely on a strong economy to sustain large ground forces, heavy artillery, and supportive units. The design tends toward resilience and steady, methodical expansion rather than fragile, high-risk tactics, with unit types that favor survivability and consistent performance across various maps.

Outside of games and fictional settings, UEF is used as an acronym for various organizations and initiatives, depending on language and context. The exact expansion and scope of the acronym can vary widely, so the intended meaning is generally clarified by accompanying text or situational context.
