Rather belatedly, the Army attempts to clear up some recent FUD (widely reported, including here) about SINCGARS. US servicemembers can use the SINCGARS radio system with confidence. Recent media articles [about Hezbollah's use of Iranian technology to defeat SINCGARS security] are wrong. The Israelis do not use the US SINCGARS system, but rather they use another frequency-hopping technology. "These articles lead people to think that SINCGARS is vulnerable, and that this technology is available to bad guys. This is not the case. The Israelis do not have SINCGARS radios. They have another frequency-hopping radio that does not have the US frequency-hopping algorithm, does not use the US communications security devices and does not use the US transmission security devices. All three provide robust protection for US SINCGARS."
It may still be safe, but it is certainly getting old, as this concluding remark, to his fellow soliders in the field, makes clear: Bowden noted that he has been working on SINCGARS since the 1980s and can answer any questions about it.
