However, these figures represent only a partial account and do not reflect the full extent of the casualties. […] This week, CIA Director William Burns penned a column in Foreign Affairs estimating the total losses of the Russian army—killed and wounded—at 315,000. At first glance, this figure might seem significantly different from our own count, but in reality, it’s not, and we regard Burns’ estimate as close to the truth.
