Final answer:
Mobility is the theater deployable communications (TDC) equipment characteristic that requires size, weight, power requirements, and equipment set-up times to be kept to a minimum.
Step-by-step explanation:
The theater deployable communications (TDC) equipment characteristic that requires size, weight, power requirements, and equipment set-up times to be kept to a minimum is Mobility.
Mobility is important to support the transportation, deployment, and operations in a deployed environment. TDC equipment needs to be easily transportable, lightweight, and have efficient power consumption to enable quick deployment and smooth operations in different locations.
For example, satellite communication systems used in TDC are designed to be compact and lightweight, making them easy to transport and set up quickly in remote or challenging environments.
