cartridge; for example, 20MM HEI, 20MM TP, or 20MM HEI-T. The second line gives the cartridge designation; for example, M254, M55A2, or M220. The last line consists of a code number that identifies the manufacturer, interfix number, lot serial number, and year of manufacture. The color of the letters has no meaning. Color Coding The color codes for the M50-configured 20-mm ammunition are listed in table 7-2. You can see exactly where colors are located on the projectile. The projectile (fig. 7-4) is divided into sections marked A, B, C, and D. The sections on the projectile match the color code to columns in the figure. By looking at table 7-2, you can identify high-explosive incendiary-tracer round M242. First, find the projectile and its color code in column A. Then, look at section A of the projectile. This section of the projectile isn’t painted; therefore, section A of the projectile remains the natural color of the metal (copper). Look at column B and find the color for section B. Refer to section B of the projectile. This area is painted yellow (high explosives), and section B1 is painted red (incendiary). Use the same procedures for sections C and D. Also note the red T markings in the section B area just outside of the B1 section. The red T, and in some cases orange T, shows the presence of an incendiary explosive (tracer). AMMUNITION CONTAINER M548 The M548 container (fig. 7-5) is made of metal. The lid is attached by quick-release latches at both ends. Figure 7-5.—Ammunition container M548 (typical). 7-5
