ITAR stands for International Traffic In Arms Regulation. It is a U.S. Law designed to reduce the proliferation of weapons and weapons technology outside the United States. Some software is affected by ITAR and as a result cannot be distributed to non-US citizens (or permanent residents). Our REDTOP-Pro and QuickShot software are subject to ITAR and as a result cannot be distributed to foreign nationals without an export license. For more information concerning ITAR please visit the Directorate of Defense Trade Controls website.
