This is probably one of the lesser know German formations of WWII. It was formed in early '43 and disbanded about a year later. I have come across a couple of references to this unit but the only thing substantial I've come up with is a short Wiki article. GAD 18 was a full division consisting of three motorized artillerie regiments, a sturmgeschutz battery, a flak bn., a battalion of motorized infantry (artillerie grenadiers?) plus other assorted units. There was a picture of 150mm Hummels, but otherwise, nothing on weapons. For most of its life, the division was commanded by Generalleutenant Karl Thoholte. In one reference to this division, I seem to remember that Hitler ordered that it LEAD an attack. The fact that the infantry BN saved the division from annihilation three times meant that the division was way far forward and my memory could be correct. Eventually, the division was broken up due to heavy casualties, with its staff and support units going to Gross Deutchland and the individual regiments turned into individual independent artillery brigades. Personally, I think a few such divisions, using older men and others who could be useful but not up to frontline combat, could have been quite helpful. They could have buttressed hard pressed areas and counter attacks. However, using them as shock troops was quite a stretch and makes one wonder what "Doc" Morrell was feeding Old GROFAZ that day!
