>The SMM revisited five “DPR” and four Ukrainian Armed Forces heavy weapons holding areas whose locations comply with the respective withdrawal lines. The SMM found that all weapons previously recorded at three “DPR” sites were in situ. An armed man guarding the facility at one of the sites claimed that he and those present at the site were part of the 16th airborne brigade from Orenburg, Russian Federation. They did not wear identifying insignia.
