Stratego

From the box -

"The CLASSIC GAME of BATTLEFIELD STRATEGY

ON A DISTANT PLANET, TWO ARMIES CLASH. WHO WILL BE VICTORIOUS?

You command an army of soldiers, machines, scouts and miners.

Devise a plan and deploy your troops. Use strategic attack and clever deception to break through your opponent's line, but beware of bombs and enemy spies. Capture the flag, and victory is yours!"

Two players position their game pieces on a chess-like board but in a configuration unknown to each other: token values can only be seen from one side.
