Beginning with the Patented Calzone Double Angle construction, the Titan Series incorporates virtually every protective feature available.  To achieve Mil Spec classification, a transportation case must survive a battery of performance tests, including the routine drop test from 4 feet to an assault by a fog and salt created environment. 

An independent laboratory administers and analyzes the performance of a manufacturer's product in meeting military specifications.  The testing criteria is so punishing, some manufacturers supplied up to 30 cases, one for each test procedure.  Calzone only needed to provide 3 cases to achieve a successful rating.
