SOCMET (smoke and obscurant countermeasures materials evaluation test)

SOCMET stands for smoke and obscurant countermeasures materials evaluation test. The expansion appears in NATO's glossary of acronyms and abbreviations, AAP-15 (2013), which is the reference for how the Alliance writes out its shorthand.

The term describes a test used to evaluate smoke and obscurant materials that serve as countermeasures. Smoke and obscurants are materials released to hide people, vehicles or equipment from observation, and a materials evaluation test checks how those materials perform. SOCMET is a NATO term, so it is most likely to be met in allied defence science and standardization material.

How NATO defines SOCMET in its glossary

The NATO glossary gives the full English expansion as "smoke and obscurant countermeasures materials evaluation test." It also provides a French equivalent, essai d'évaluation des fumées et obscurcissants utilisés comme contre-mesures. Both forms are in the same AAP-15 glossary, which presents NATO terms in English and French.

The French wording is useful for bilingual bid teams. It confirms that the test concerns smokes and obscurants (fumées et obscurcissants) used as countermeasures, and that the activity is an evaluation (essai d'évaluation).

Smoke-screen testing in NATO archival material

NATO archival material describes work closely related to what SOCMET names. One NATO archive document discusses smoke-screen testing and evaluation. Its subjects include field tests, materials identification, test design, data evaluation and recommendations.

The same document states that smoke-screen performance was evaluated in relation to anti-infrared smoke systems for the self-protection of armoured fighting vehicles. That places smoke evaluation in a vehicle protection setting, where the material must work against observation in the infrared band as well as the visual one.

A separate NATO archive item, the report by the chairman of Sub-Panel VI on multi-spectral screening smokes and smoke munitions, shows that NATO working groups have also addressed screening smokes and the munitions that deliver them. NATO archival material on this subject also covers smoke-screen performance, smoke-materiel standards, laboratory and field measurement techniques, and materials-evaluation programmes.

Why obscurants matter to Canadian defence

Smoke and obscuration are recognized Canadian defence topics. The Canadian Army Journal article Back to the Future discusses smoke obscuration as a military capability. It describes obscurants as affecting both visual and thermal observation.

That description matches the purpose of a countermeasures materials evaluation: confirming that a smoke or obscurant material does its job against the sensors and observers it is meant to defeat.

What SOCMET means for a supplier bidding on Canadian public contracts

SOCMET is a NATO-defined abbreviation, and a supplier who meets it in a tender document should treat it as a reference to evaluation testing of smoke and obscurant countermeasure materials. Read how the solicitation defines the term, and note which test methods, standards or reference documents it cites.

• Check whether the document uses the NATO expansion given in AAP-15 or defines the term in its own wording.
• Look for the test design, field test and data evaluation requirements that the solicitation attaches to any evaluation.
• Confirm whether the requirement concerns visual obscuration, infrared or thermal obscuration, or both.
• In bilingual documents, compare the English and French wording against the NATO glossary pairing.

Bid teams working on smoke, obscurant or vehicle self-protection requirements can use the NATO glossary and archival material above to align their terminology with allied usage.
