1991
Battle of 73 Easting
The setting
Iraqi desert near the 73 Easting north-south map grid line, southeastern Iraq
Open, featureless desert with no significant terrain references - units navigated by the UTM grid line (the '73 Easting') itself, which gave the battle its name.
Reveal the outcome
Recorded sideUnited States (2nd Armored Cavalry Regiment, VII Corps; theater commander norman-schwarzkopf)
Recorded resultDecisive one-sided victory
U.S. armored forces destroyed Iraqi Republican Guard tank and mechanized units in a short, lopsided engagement during the ground offensive. (Schwarzkopf was overall theater commander; tactical action was led by subordinate units.)
How the atlas explains it
US thermal imaging, longer-range and more accurate gunnery, superior training and combined-arms coordination produced total overmatch; the sandstorm that should have favored the defender instead let the Americans destroy Iraqi armor before it could effectively return fire.
What followed
A defining demonstration of post-Cold War US armored superiority and the value of thermal/sensor technology; the battle's exhaustively reconstructed data later informed military simulation and doctrine.
