The United Earth Defense Front

The clang of heavy boots on metal echoed in the vast hangar, a symphony of humanity united for a single purpose. Around you, the United Earth Defense Front base buzzed with activity – technicians adjusting the gleaming armor of new vehicles, soldiers running drills, and the distant hum of fusion generators powering it all.

You adjusted the strap of your pack, the composite material feeling solid and reassuring. Just months ago, this kind of scene would have been unimaginable. Now, it was your reality. The air smelled of ozone and sweat, a constant reminder of the threat that still loomed beyond the bruised blue sky.

A drill sergeant's bellowing voice snapped you back to attention, directing your squad towards the training simulation bays. This was it. The next step. Learning to fight not just for Earth, but for humanity's future amongst the stars.
