Buses plastic model kits are produced in various scales from "large automobile" 1/24 to "tank" 1/72 or "railway" 1/87. Accordingly, large-scale models of buses can be conditionally divided into civilian and military. Sometimes some kinds of models of civilian buses were called for military service and were painted in camouflage or khaki color. Such buses were modified for the needs of the army - windows were remade, cargo compartments were added, doors were made bigger for the possibility of carrying large-sized loads, etc.
