Terminal Learning Objective
Action: Introduction to Modernized Demolition Initiators
• Developed in the late 40s
• Used in Civilian Market
• Introduced to the Army in 1996
HISTORY
CONSIDERATIONSCONSIDERATIONS
� MDI DOES NOT CHANGE CHARGE EMPLACEMENT OR SETUP
� MDI IS STRICTLY AN IGNITION SYSTEM CHANGE.
CAPABILITIESCAPABILITIES� Standard military demolition missions
� Deepwater up to 30 meters
� Quarrying(with special application).
� Instant or delay initiation
� Eliminates accidental initiation from static, transmitters, or electrical discharge
� Hybrid (two types of firing systems)� MDI Stand Alone
� MDI/Det Cord, Det Cord/MDI
