Stowage on the mudguards is what makes a tank look used, and quarter scale is no exception. Resin detail sets for military vehicle models in 1:48 offer 3D-printed shovels, pickaxes, crowbars, starting cranks, jacks, headlamps and wire cutters, usually several to a pack, so you can equip a whole column at once.
Printed detail at this fineness clearly outdoes the stowage supplied in boxes, as you can compare for yourself on 1:48 military vehicle kits. General advice on removing parts from their supports and gluing them is in the resin detail sets hub. Quarter-scale armour also gains from metal grilles in 1:48 photo-etched parts.
