Over time Silmid have gained extensive knowledge of military and defence specifications and standards for armed forces all over the world, including the following;
- DEF STAN
- NATO
- MIL-PRF
- MIL-SPEC
- DOD
- DCSEA
Military equipment can be used in extreme environmental conditions, specs and standards have evolved from the need to ensure proper performance, maintainability and reparability (MRO) and logistical usefulness of military equipment. MRO and logistics were big drivers behind standardisation the need for greater interchangeability during times of conflict, during World War 2 allied forces were busy standardising and cataloguing. The U.S. AN- cataloguing system (Army-Navy) and the British Defence Standards (DEF-STAN) are great examples of this.
