Originally applied to any group of infantry primarily armed with projectile weapons, artillery has over time become limited in meaning to refer only to those engines of war that operate by projection of munitions far beyond the range of effect of personal weapons. These engines comprise specialised devices which use some form of stored energy to operate, whether mechanical, chemical, or electromagnetic. Originally designed to breach fortifications, they have evolved from nearly static installations intended to reduce a single obstacle to highly mobile weapons of great flexibility in which now reposes the greater portion of a modern army's offensive capabilities.
with a 17cm gun
lulwut, thats pretty awesomeO!
lol this si GW tiger with 170mm gun
sigh
GW Tiger is only short for Geschützwage [weapon carrier]) and Tiger means that the chassis was from an enlargered Tiger II hull.
But this is not the correct designation, the real name of this series was GRILLE series.
And yes, you were right about the armament, the model in this picture has a 17cm gun, however it was also planned to convert Grille 17 into Grille 21 armed with 210mm gun.
