Military vehicle kits are generally produced by manufacturers who do not publish skill level ratings for their kits. Most military vehicle kits are fairly straight- forward to build and can be assembled by the intermediate level builder.
The facet of military vehicle building that raises the level of dificulty is the painting and finishing of the model. Almost all military vehicle kits are molded in a color which approximates the basic color of some version of the real vehicle, but painting is usually necessary to give the kit a finish like that shown on box art.
