"...anybody know how many of those fearsome Tiger II tanks were deployed in this offensive?"

I'm only seeing two battalions, the 501st (First SS Panzer) and 506th (Sixth Panzer Army).

At full strength a battalion had 45 Tiger IIs, so we're looking at maybe 90 total, out of 1,800 total German tanks in the battle.
The balance were Panzer IVs, Panthers & Tiger Is.

Those things look pretty brutal. The Germans were always coming up with the most fearsome artillery. German engineering.

Thanks for the info. Did some further checking and 501 Schwere Panzer Abt. was attached to Kampfgruppe Peiper, so half of the available Royal Tigers were effectively lost once Peiper was surrounded and cut off from resupply. In column Peiper liked to lead with a Panther as it was his favorite tank, instead of the Royal Tiger. Or he would also lead with a captured enemy vehicle. But Peiper valued the Panther’s maeuverability and higher rate of fire.
