Nestled in a dense forest, the Ukrainian military base appears abandoned and destroyed, its command center a burned-out husk, a casualty of a Russian missile barrage early in the war.
Not far away, a discreet passageway descends to a subterranean bunker where teams of Ukrainian soldiers track Russian spy satellites and eavesdrop on conversations between Russian commanders.
On one screen, a red line followed the route of an explosive drone threading through Russian air defenses from a point in central Ukraine to a target in the Russian city of Rostov.
The underground bunker, built to replace the destroyed command center in the months after Russia’s invasion, is a secret nerve center of Ukraine’s military.
There is also one more secret: The base is almost fully financed, and partly equipped, by the C.I.A.
