Lessons from AUSA 2026: The Changing Logic of Armored Warfare

cross-posted from: https://lemmy.ca/post/72456282

One of the most striking exhibits at this year's Association of the United States Army (AUSA) Annual Meeting and Exposition was not a main battle tank (MBT). On the opening morning, October 12, GM Defense rolled out an uncrewed ground vehicle built on a Chevrolet Silverado 3500HD chassis, pitched for "silent logistics and casualty evacuation" and fitted on the show floor with a counter-drone laser.

A few minutes’ walk away, in a tent on 9th Street, Ukrainian companies were showing interceptor drones, jammers and robotic carriers that their own military units order in large quantities. A fashionable reading follows: the main battle tank is finished, and the future belongs to light trucks, robots and swarms.

That reading confuses a change in where survivability comes from with the disappearance of a platform. The evidence from Ukraine, from US Army testing and from the exhibition itself points to a narrower and more demanding conclusion. Survivability on a battlefield monitored by large numbers of inexpensive sensors can no longer depend primarily on armor thickness. It increasingly depends on the formation as a whole: protection, mobility, concealment, dispersion, electronic resilience, active protection, counter-drone defenses, logistics and uncrewed systems must work together. The force that emerges combines tanks, protected four-wheel-drive vehicles, tracked carriers, ground robots, first-person-view (FPV) drones and counter-drone layers, each covering gaps in the others. The more consequential question is whether armies can redesign their combined-arms formations quickly enough to preserve the tank's battlefield utility.

Any assessment of AUSA must distinguish what a defense exhibition demonstrates from what it merely suggests. The 2026 meeting, held October 12–14 at the Walter E. Washington Convention Center in Washington, advertised more than 750 exhibits and over 40,000 attendees, and for the first time added an outdoor exhibit area across 9th Street. A concept displayed at an exhibition reveals what a company believes the Army may want to acquire; it does not establish operational performance, affordability or the likelihood of procurement. The distinction between demonstration, adoption, repeat procurement and production at scale runs through everything that follows.

The outdoor area housed the event's clearest symbol of that gap. Organized by the US firm Fenicks Group, the Ukrainian Defense Tech Pavilion was advertised as showcasing 17 Ukrainian companies. The official exhibitor listing included additional entities, among them Ukraine's Third Army Corps, a military formation rather than a commercial company.

...

Even discounted for those limits, the evidence supports a narrower conclusion: inexpensive airborne weapons account for a substantial share of reported vehicle damage in Ukraine, while the distinction between a mission kill and the permanent destruction of a vehicle has become operationally important. A tank that loses its tracks, optics or engine in a drone attack may be removed from combat even if its crew survives and the vehicle can eventually be repaired. Comparing purchase prices misleads, which is why CSIS has urged the Pentagon to judge drones by price per mission: the true cost of an FPV includes operators, training, radios and the many drones lost to jamming before reaching a target, while the cost of a damaged vehicle includes recovery, repair time and the operation it was meant to enable. On this basis, the economic exchange may still favor the drone in many circumstances, although the advantage depends on mission success, target value, repair requirements and the availability of replacement systems.

Steel has not stopped mattering, but each layer of protection now carries a price in weight and mobility. Passive armor and explosive reactive armor (ERA) remain important protective layers. RUSI documented a Ukrainian tank platoon operating captured Russian tanks that reportedly sustained between two and 12 hits per operation and remained serviceable after their armor packs were replaced. Improvised screens and so-called "cope cages" can provide limited protection against some top-attack threats but are not uniformly effective. Ukrainian officers interviewed by RUSI argued that Russia's fully enclosed "turtle tanks" were counterproductive because their protective structures restricted turret movement. Active protection systems (APS), which detect and intercept incoming munitions, were designed mainly against missiles and rockets, and adapting them to slow, small and numerous drones remains an engineering problem [my edit: this is primarily a problem for russia which is failing to adapt]. Although onboard jammers can disrupt radio-controlled drones, they are largely ineffective against fiber-optic-guided systems. Meanwhile, additional protective equipment increases vehicle weight, potentially reducing the mobility and fuel endurance required for dispersed operations.

The heavy-armor case deserves its full weight here. Tanks remain among the most capable ground platforms for combining protected direct fire and shock action in a vehicle designed to support assaults against defended positions. Nothing displayed at AUSA demonstrated that lighter vehicles or uncrewed systems could replace this combination across the full range of combat tasks.
