What is the first action to take when experiencing loss of communications?

When experiencing a loss of communications, the first action to take is to attempt to contact any or all units/assets. This is essential because it allows for immediate efforts to re-establish communication with other team members or command, which is critical in maintaining situational awareness and operational safety. Reaching out to all available resources ensures that any possible means of communication can be utilized to relay important information or receive instructions.

Utilizing secondary radios, signaling with colored smoke, or switching to cell phones may be necessary steps to take, but they should be considered as part of a broader response plan after the initial attempt to regain communication has been made. The priority is to re-establish the line of communication as quickly as possible to ensure everyone's safety and the success of the mission.
