The Allies (namely Great Britain, France and Poland in 1939) did not have any (zero) armored divisions at the beginning of World War II. The index of military strength in September 1939 was the number of divisions that each nation could mobilize.

Against Germany’s 100 infantry divisions and six armored divisions, France had 90 infantry divisions in metropolitan France, Great Britain had 10 infantry divisions, and Poland had 30 infantry divisions, 12 cavalry brigades, and one armored brigade (Poland also had 30 reserve infantry divisions, but these could not be mobilized quickly). A division contained from 12,000 to 25,000 men. And, again, although the Allies did have a large number of tanks, they had no armored divisions at the start of the war.
