It evolved from a WW1 game, where the general warfare is "sit in your trench, attack, die/survive, hog enemy trench, repeat", but it featured some unit specific tactics, like when to use grenades and the comanders ability to call in air and artillery strikes (the 1917 commander was quite useless, only armed with a pistol and gave your men a buff...woo<.<), and it is really a hard nut to crack an enemy tank.
Also, in real warfare, u usually sit in your cover to not get shot at anyway. And only come out to advance or take some shots at the enemy position.
I liked the game, and made it through both campains...mainly the upgrade system between the fights totally made me go on.
And it´s called Wehrmacht >.<
