Overmatch is a concept in modern military thinking which prizes having overwhelming advantages over an adversary to a more significant margin than in traditional warfare. It is related to military superiority.^[1] Overmatch uses a military force's "capabilities or unique tactics" to compel the opposing forces to stop using their own equipment or tactics, as doing so would lead to their own defeat or destruction.^[2] By fielding the right mix of capabilities, the commander can present multiple dilemmas to the enemy, thus compelling the enemy to withdraw.^[3]: 57:00

According to the US Army, the definition of overmatch is "the concept where my (insert lethality system here) can willfully and without prejudice or luck defeat your (insert your protective system here)."^[4]

According to Raytheon, overmatch is a verb which means "to defeat threats at every level – strategic, tactical and technological."^[5]

According to Ben Barry, "overmatch is a very polite, clinical way of saying could be defeated.”^[6]

From 2017, after the Annexation of Crimea by the Russian Federation, and the dismissal of the need for counter-insurgency for a second time, the US Army emphasized overmatch in their modernization effort.^[14]

In 2017 a task force was formed to modernize the Army. Its recommendation was to form the Army Futures Command, to engage in systematic development of capabilities to overmatch its adversaries.^[15]

In 2021 the 40th Chief of Staff of the Army identified^[16]

"Overmatch will belong to the side that can make decisions faster. To meet emerging challenges, the Army is transforming to provide the joint force with speed, range, and convergence of cutting edge technologies that will generate the decision dominance and overmatch required to win the next fight.”

Overmatch has been criticized as unsustainable in the long term^[17] and requiring immense investments in the military and cutting-edge technologies.^[18]
