INTRODUCTION
Today, the Army uses many different types of telephones and switchboards. The mission involved and
units employed will determine the equipment requirements and their reconfigurations.
1. Types of telephones. We can divide the tactical telephones into two major groups-common-battery
and local-battery equipment. Normally, units at company and battalion level use local-battery
equipment. At the brigade level and up, we use common-battery equipment. Table 1-1 provides a list of
the telephones and switchboards most commonly used. Part A of this lesson provides their technical
characteristics.
