The Counterfactual War. Conquistadors!, #2

The Protectorate - an interdimensional empire that has conquered five timelines so far - has set its sights on ours. Led by a man willing to risk everything for power and conquest, armed with technology a hundred years ahead of ours - technology promising salvation to its allies and doom to its enemies - and drawing on a far deeper military history, the Protectorate Expeditionary Force has arrived to invade and incorporate our world into the greatest empire the multiverse has ever known, or die trying.
The United States has won a desperate battle against the crosstime invaders, but large swathes of the country remain under enemy occupation, the struggle to understand invader technology has barely begun and a new invasion force has appeared in the Middle East. As the country staggers and threatens to collapse, the military prepares for a major offensive that could make or break the war, while - deep in the heart of Texas - the invaders prepare a plan of their own .One battle has been won.
The war is far from over.
