Judging from the recent PLA Daily articles and internet photo "releases", the 8th LH brigade of the 38th Group Army, Beijing MR has become the 2nd LH unit armed with the latest Z-10 attach choppers (6th squadron). It is interesting to note that the 8th is also home to the Z-19 light attack helicopter (5th squadron).
After two years of service with the 5th LH brigade, it is clear that the CMC is now ready to expand its Z-10 footprint
This Z-10 is obviously at Baoding (8 Army Avn Bde), where 12 large hangars (for MI-17) and 9 small hangars (for Z-10), all camouflage and with round roofs, have been built by 2011. They seem to be also constructing 8 large hangars (for Z-8?).
There are also round hangars at Sanshui-Daliao (6 Army Avn Bde), but they are not camouflaged and are in two consecutive rows of 10, not separated like those at Baoding.
Since Z-8 and Z-10 appear to go together, perhaps we should expect the next Z-10 squadron to be formed in 26 GA 7 Army Avn Regt (Bde?).
