Comm Unit
Item 1
Personal comm units integrated into armor have some voice-activated capabilities; you can communicate with other comm units in audio-based formats and receive responses without needing a free hand, but typing a message, browsing the infosphere, or using an app requires the use of at least one hand.
Comm units that function at longer ranges aren't as portable; they include built-in generators that provide the necessary amount of power and rely on active Drift beacons to communicate. Short-term use of these units can be purchased in most major settlements.
