Heavy Weapons Company
Three infantry rifle companies, a headquarters & headquarters company, and a heavy weapons company together made up the infantry battalion. The headquarters & headquarters company was referred to by that name, or as “HHC”. The other companies of the battalion, however, were known as the “letter companies.” Identification of the “letter companies” ran consecutively through the three battalions of the infantry regiment: 1st Battalion contained A, B, and C Companies (rifle companies) and D Company (heavy weapons); 2nd Battalion contained E, F, and G Companies (rifle companies) and H Company (heavy weapons); 3rd Battalion contained I, K, and L Companies (rifle companies) and M Company (heavy weapons). The letter J was not used, as it could be confused with the letter “I” when handwritten
