They reference the war zone article, which contains the relevant quote but nothing in the vice article that I could find directly states that the experiment failed to confirm the effect. The text you quote certainly does not. EDIT: I don't know what you mean about the "latest update". The original War Zone article was discussed here two days ago and it already contained the DoD quote, while the Vice article is dated yesterday. It's either very sloppy journalism or intentional clickbait.
