The company MST (Sanko Makina and ASKO Holding) has direct and close ties to the Turkish defense industry. It serves as an important supplier of specialized military engineering equipment for Turkish security forces. Here is exactly how the company is connected to the defense sector: 1. Production of Armored Construction Equipment: Ordinary construction machinery is vulnerable in combat zones. MST develops and manufactures armored backhoe loaders and telehandlers specifically designed for military needs. The cabins, engine compartments, and vital components of these machines are protected by armor capable of withstanding small arms fire and improvised explosive device (IED) blasts. 2. Supplies for the Army and Police: The primary customers for MST's military products are the Turkish Armed Forces (TSK), the General Command of the Gendarmerie, and the General Directorate of Security (Police). 3. Specific Applications: MST's military equipment is actively used by engineering troops and special forces for the following tasks: • Digging trenches and building defensive berms on the front lines; • Dismantling barricades, destroying militant shelters, and clearing streets during anti-terrorist operations (such equipment was heavily used by Turkish security forces during urban operations in the southeastern part of the country); • Safely neutralizing explosive devices on roads; • Constructing and fortifying military outposts and bases. 4. Integration into State Defense Programs: MST works in close cooperation with the Presidency of Defense Industries (SSB) of Turkey. The production of indigenous armored engineering equipment is part of Turkey's state strategy for import substitution and ensuring the national army's independence from foreign suppliers. 5. Participation in Defense Exhibitions: The MST brand regularly showcases its military developments at major international arm
