The choice of etch is deepest in 1:35, because it is the main armour scale. You get radiator grilles for the Tiger, Panther, T-34 and StuG III, thin mudguards, stowage bins with working hinges, chain, and the slat armour and appliqué plating of armoured vehicles from current conflicts.
Sets are created for particular kits, so check compatibility against your own among 1:35 military vehicle kits. If sheet brass is new to you, read the folding and gluing notes in the photo-etched parts for military vehicles hub first. And since paint follows the metalwork, clean camouflage edges come from 1:35 paint masks.
