This is an old trick-taking game which incidentally teaches the player the ranks and branches (infantry, cavalry, artillery, engineers) of the military. Originally published in 1915, it appears to have been bought by Parker Brothers and reissued in 1919 under the name Militac (although the cards still say Tactics on the back). [Note: The Militac Game Co. of Dayton Ohio first published the Militac game in 1910.]
