One of the most iconic photos of the Sherman in WW2 was with sandbags mounted as an effort to reduce the effectiveness of the panzerfaust.
The options for me were to model the tanks using green stuff… too ambitious!! or Peter Pig offers a model with the sandbags.
The Sherman model is all metal and has a nice bit of heft.
A comparison of the Peter Pig and PSC sherman 76mm
Here it is with the PSC M4A3 76mm and the Battlefront M4A1 75mm
