Field Report: Clans, pdf:
Page 13: Deployment Status, Delta Galaxy:
To me it looks like the 65th Mechanized Strike Cluster has been accidentally renamed to the 99th Mechanized Strike, especially since Beta Galaxy above it also has the last cluster beginning with 99th. (See FM:Updates, p. 71 and FM:CC, p. 68 for Delta composition)
Suggested fix:
Change 99th Mechanized Strike in Delta Galaxy to 65th Mechanized Strike.
