Wehrschach, also called Tak-Tik, was published by the German Army, the "Wehrmacht" in 1938.
On an Board with 11 x 11 squares you play a chess-like game with 18 pieces per player, for instance the "Jagdflieger" or the "Panzerkampfwagen", all 3D and of Bakelite. These can move only vertical or horizontal, but a different number of squares, with the exception of the "Panzerkampfwagen", which moves like the knight in chess, but without over jumping other pieces.
The board is divided through diagonal lines and two more lines crossing the 3rd and 9th row indicating walls and two special fields with "water".
Gameplay was more or less like chess, but with some special rules for the different figures.
