From Glantz " Zhukov´s greatest defeat"

On the Rzhev area operation late 1942

In the Center, the combined strength of the Kalinin and Western fronts, backed up by Moscow defence zone, numbered almost 1,9 million men, with 24,000 guns and mortars, 3,300 tanks and 1,100 aircraft. This represented 31% of the manpower, 32% of artillery, almost 50% of armor, and over 35% of the total Soviet strength, and their massive strength was concentrated on only 17% of the overall front.

( Wow! Just how did the Germans manage to keep that offensive from breaking through....)
