Also, Juno is a H135 and not a H135M.
Haven't been able to read the story on Flight due to the paywall, but from the headline and the standfirst it seems that the Gazelle is being replaced by the H135, not the H135M. Happy to be corrected if the article says otherwise.
If so, it does raise an interesting point as to what the AAC plans to do with it as surely it won't have the same battlefield support role as the Gazelle had, and if not then what is the point of it?
