1. SINCGARS FAMILIARIZATION AND OPERATION
Primary Instructor: SGT SPENCER Assist Instructor: SGT LEWIS th MP CO

2. TASK: Communicate via Tactical Radio in a Secure Net
CONDITIONS: Give an operational radio net with an SOI, fill device with appropriate fills, fill cable, and an operational distant station
STANDARDS: Establish voice communications with the distant tactical radio/network within three minutes
References: TM TM 2

3. METHODS OF COMMUNICATION
VISUAL SIGNALS (Hand signals, Semaphore)
SOUND SIGNALS (Speaking from one person to another)
MESSENGER (Sending another person to deliver either a written or voice message)
WIRED SIGNALS (Land-line telephone, DSVT/DNVT, TA-312, TA-1)
RADIO COMMUNICATIONS (SINCGARS, PRC-77, PRC-127)

4. PURPOSE
Provide familiarization / refresher training on SINCGARS radios through conference style instruction and hands – on practical exercises. Ensure personnel are capable of operating SINCGARS radios in Frequency Hopping Modes. Ensure personnel are trained to perform both hot and cold start net openings.
