This Distinctive Environmental Uniform (DEU) belonged to Commander William Kern, a naval medical officer.

Canada abolished the tri-service uniform in 1985 and replaced it with DEUs. Navy, army, and air force personnel received summer and winter outfits that differed between the three services. While the new naval uniforms were superficially similar to their Royal Canadian Navy predecessors, they differed in a number of ways. Most notably, they were black rather than dark blue. The rank stripes on the jacket sleeves also differ; the "executive curl", a small circular loop on the uppermost stripe, did not appear on the naval DEU.
