Is everyone aware that there are ham radio operators specially licensed to pass messages between US armed services personnel, their families, and friends? The information is available online and there are separate systems for Army, Air Force, and Navy-Marines. One helpful starting point is: www.navymars.org. Message traffic through the MARS networks isn't as swift as email or telephone but the operators are dedicated volunteers. As with other activities at which amateur radio operators work, there is no charge for the service.
