Type II, style 1. This plate is intended for use on internal combustion engines to provide overhaul data.

Type II, style 2. This plate is intended for use on military equipment to show modification work order data.

Type III. This plate is intended for general use on military equipment to provide special identification, instruction, designation, and other miscellaneous data (see 3.3.2) that is either not provided for in the format of the referenced military standards (MS) or requires a special format due to inadequate space available for mounting and data that cannot be inscribed in legible form. Equipment includes all vehicles (both wheeled and tracked), combat vehicles, trucks, trailers, semi-trailers, dollies, personnel, utility carriers, and vehicles used in field construction and engineering work. Special data is to be furnished by the design activity of the equipment.
