Understanding "Correlation of Forces" in Ukraine Counsels Caution for the US
In Western military circles, it’s common to refer to the “balance of forces” — the lineup of tanks, planes, ships, missiles, and battle formations on the opposing sides of any conflict. If one has twice as many combat assets as its opponent and the leadership abilities on each side are approximately equal, it should win. Based on this reasoning, most Western analysts assumed that the Russian army — with a seemingly overwhelming advantage in numbers and equipment — would quickly overpower Ukrainian forces. Of course, things haven’t exactly turned out that way. The Ukrainian military has, in fact, fought the Russians to a near-standstill. The reasons for that will undoubtedly be debated among military theorists for years to come. When they do so, they might begin with Moscow’s surprising failure to pay attention to a different military equation — the “correlation of forces” — originally developed in the former Soviet Union.
That notion differs from the “balance of forces” by placing greater weight on intangible factors. It stipulates that the weaker of two belligerents, measured in conventional terms, can still prevail over the stronger if its military possesses higher morale, stronger support at home, and the backing of important allies. Such a calculation, if conducted in early February, would have concluded that Ukraine’s prospects were nowhere near as bad as either Russian or Western analysts generally assumed, while Russia’s were far worse. And that should remind us of just how crucial an understanding of the correlation of forces is in such situations, if gross miscalculations and tragedies are to be avoided.
The Concept in Practice Before Ukraine
The notion of the correlation of forces has a long history in military and strategic thinking. Something like it, for example, can be found in the epilogue to Leo Tolstoy’s epic novel, War and Peace. Writing about Napoleon’s disastrous invasion of Russia in 1812, Tolstoy observed that wars are won not by the superior generalship of charismatic leaders but through the fighting spirit of common soldiers taking up arms against a loathsome enemy.
Such a perspective would later be incorporated into the military doctrine of the Russian Bolsheviks, who sought to calculate not only troop and equipment strength, but also the degree of class consciousness and support from the masses on each side of any potential conflict. Following the 1917 revolution in the midst of World War I, Russian leader Vladimir Lenin argued, for example, against a continuing war with Germany because the correlation of forces wasn’t yet right for the waging of “revolutionary war” against the capitalist states (as urged by his compatriot Leon Trotsky). “Summing up the arguments in favor of an immediate revolutionary war,” Lenin said, “it must be concluded that such a policy would perhaps respond to the needs of mankind to strive for the beautiful, the spectacular, and the striking, but that it would be totally disregarding the objective correlation of class forces and material factors at the present stage of the socialist revolution already begun.”
For Bolsheviks of his era, the correlation of forces was a “scientific” concept, based on an assessment of both material factors (numbers of troops and guns on each side) and qualitative factors (the degree of class consciousness involved). In 1918, for example, Lenin observed that “the poor peasantry in Russia… is not in a position immediately and at the present moment to begin a serious revolutionary war. To ignore this objective correlation of class forces on the present question would be a fatal blunder.” Hence, in March 1918, the Russians made a separate peace with the German-led Central Powers, ceding much territory to them and ending their country’s role in the world war.
