Much like Tom said, like most of the AH/MMP HASLs that have come before it, FB features mostly (>90%) historical names for all of the nationality leaders. For the Germans, 51 of the 53 leaders fought inside the city either with one of the 2 SS Divisions, the 13th Panzer, the Feldherrnhalle, or the Europa alarm battalion.
For the Axis Hungarians, of the 57 leaders provided, 55 were there in Budapest with the vast majority being the squad and company leaders from the Vannay Battalion. The 1-4-9 Ungvary hero is in homage to the author of one of the books from which much of the historical information was taken from. The 1-4-9 Zwack hero is in homage to the US Army General that wrote the MHQ article that initially sparked my interest in the siege of Budapest. General Zwack's father was in Budapest during the siege.
On the Soviet side, of the 50 leaders 46 fought in Budapest. Three of the other four (Blantonov, Alonsonev, and Noahvich) are playtesters, while the fourth is 7-0 Sgt. Argentov (ya, go figure).
The last batch, the Buda Volunteer Regiment has 36 leaders, 30 of whom belonged to the BVR. Nevekin and Szamveber are historians who provided me information on the battle, Harviala did playtesting, Hajos and Borsanyi dug up a bunch of really useful information for me, and Kirkaldy did all the initial map development and a lot of the initial concept work.

Same goes for VotG, many of the German & Soviet leaders were historical names, from division COs to regimental, battalion and company COs.
I love it when HASLs use the historical leader names, not only a nice touch but honors their memory (sort of).
