Experts from Dstl have been working with soldiers on a live fire exercise to ensure they are equipped with the most effective kit possible.


Dstl News Release, Porton Down, 23 August 2022: Using a specially designed obstacle course, the Defence Science and Technology Laboratory (Dstl) team conducted a pilot study to assess the effects of the SA-80 L85A2 versus the L85A3 rifle with six soldiers from 5th Battalion, The Rifles.

The Soldier Weapon and Equipment Assessment Tool (SWEAT) tests the impact of soldier equipment on firing accuracy, consistency, speed and mobility. These tests were executed as part of NATO Science and Technology Organization (STO) Research Task Group SAS-145. This research is overseen by STO’s System Analysis and Studies (SAS) Panel, NATO’s Expert Panel for Analytical Advice, which promotes the exchange of trial data and enhance interoperability within the Alliance.

SWEAT trial – Jon from Dstl said: “The idea behind the SWEAT course is that anyone can measure the effects of future soldier capability, such as a new weapons system, new boots, a new helmet or new body armour, and assess the effect that will provide upon the individual’s lethality.

“This course for the UK, in the future, will be used to measure the effects of new capabilities for soldiers.

“The final objective of the trial is for it to be used and developed by NATO nations to develop their own courses that are similar enough to allow interoperability between nations.”

The 2-day exercise took place on Salisbury Plain using a UK SA-80 L85 A2 and updated A3 variants of the individual weapon. Participants ran the course twice to compare results. The course consisted of 14 firing points and 36 actions, requiring soldiers to engage targets ranging from 25m to 400m from a variety of firing positions.

Elizabeth, of the US Army, observing on behalf of NATO, said: “It’s doing something novel and innovative.

“Taking different components that have been separated, so lethality, survivability and mobility – bringing them into a course that comprehensively tests soldier systems.

“ It’s a much better evaluation than has existed before.”

Editor’s Comment: Although this News story was released today we suspect the SWEAT Trial comparing SA80A2 and SA80A3 might actually have been conducted a few months ago.
