15cm sIG auf PzKpfw 38(t) Ausf. H 'Grille' (Sd. Kfz. 138/1)
    Copyright (C) 1996 by James Lowry (jlowry@tfb.com).

        In a desire to provide fully tracked artillery support, the 150mm
    Infantry Gun was placed on a Panzer 38(t) H chassis.  An oval superstucture
    encompassing most of the top deck was built around the large gun and crew.
    90 vehicles were built, starting in April 1943.
        The adjusted cost is pre-WWII even though this variant was developed
    after the war started.
        I used _PzKpfw 38(t) in Action_ by Charles K. Kliment and Hilary L.
    Doyle as reference in designing this vehicle.
        The Grille H (v. 1.0) is a TL 6 vehicle [Mar. 96 errata sheet] with a
    new weapon and my armor sloping table.

    Infantry Gun (TL 6)
        An infantry gun is a short-barreled, lightweight, direct-fire howitzer.
    The 150mm IG is $40,000, 2,300 lbs., 60 cf, HT 100 and requires a crew of
    two. The ammunition is incompatible with that of the 155mm Howitzer's, but
    uses the same statistics.
