The main barrier I see to this reaching FA class is the lack of detail which is available on the unit's combat history in 1944 and 1945. You've clearly looked everywhere for material on this, so it's not your fault, but it does form a significant limitation to the article. On a smaller note, the article's lead should be expanded to two paragraphs before this goes to FAC as well as the current lead is a bit short given the length of the article.
