Verdict
Edge: Peru

Peru possesses a decisive conventional overmatch in air and naval domains, making it the clear victor in a high-intensity conflict. Ecuador’s military is currently structured for policing duties and lacks the heavy platforms required for territorial defense against a mechanized peer.

Domain by domain
Air Power Edge: Peru
🇪🇨 EcuadorRelies on turboprop Super Tucanos for COIN; lacks supersonic interceptors or air defense depth.
🇵🇪 PeruOperates supersonic combat jets (Mirage 2000, Su-25) with active procurement for 4.5 gen fighters; distinct air superiority capability.
Land Warfare Edge: Peru
🇪🇨 EcuadorLight infantry focus with limited armor (Leopard 1V) optimized for urban and jungle patrols rather than heavy maneuver.
🇵🇪 PeruMechanized force with MBTs (T-55), new 8x8 armor, and precision artillery (PULS); standardizing to NATO caliber.
Maritime Edge: Peru
🇪🇨 EcuadorCoastal defense and EEZ patrol focus; aging frigate fleet with limited projection capability beyond the Galápagos.
🇵🇪 PeruBlue-water ambition with LPDs and a major frigate/OPV construction program (Hyundai partnership); capable of amphibious projection.
Logistics Edge: Peru
🇪🇨 EcuadorHigh dependency on imports and donations; strained by continuous internal deployment and fiscal deficits.
🇵🇪 PeruDeveloping domestic manufacturing (SIMA, SEMAN, FAME) for sustainability; complex mix of legacy Soviet and new Western gear.
Wildcards
  • The Amazon Theater The dense jungle terrain of the border region severely degrades the advantage of Peru’s heavy armor and advanced sensors, leveling the playing field for Ecuador’s light infantry.
  • Internal "Second Fronts" Both nations face significant internal threats. Ecuador is fighting a war against gangs; Peru battles VRAEM insurgents. A state-on-state war could trigger massive internal destabilization or uprisings in either capital.
  • US Intervention As a strategic partner to both (Peru as MNNA, Ecuador via SOFA), the United States would likely leverage intelligence cutoffs and logistical halts to force an immediate ceasefire, freezing the conflict before decisive victory.
