10. Summary
It is necessary to determine the following items for armour protection selection:
It is necessary to determine the following items for armour protection selection:
- Required protection level as per ballistic-proof / splinterproof firmness
- Shell material / armour packet material (operating conditions)
- Harness system type (for helmet)
- Shape (ergonomics)
- Scope (foot troops, special forces, armoured vehicle operator, mine picker, sniper, flamethrower operator, etc.)
