Thanks for that older link and the new information. I did search for old postings by Battalion in the titles but not in the text, so if others find similar situations, please let me know.
The Matrix still had the 51st as one of the "Other Battalions" with little information and no page of their own. With you information I have now moved the 51st to the "Reorganized Units / Reinforcements" and put the links to the two postings as well as the new 51st page on the Matrix Summary Table. If you have additional information or want to edit the information I "leeched" from your posts. please go ahead, now or in the future.
