Could tanks become obsolete in future wars?

“Obsolete” is a word historians learn to distrust. Cavalry didn’t vanish; it transformed. The tank itself was a response to trench warfare, and then it adapted through WWII into combined-arms maneuver. The lesson from 1940–1945 and the Cold War is consistent: armor alone gets punished, but armor integrated with infantry, artillery, engineers, air power, and reconnaissance can be decisive.

What changes in the drone/missile era is not the need to seize and hold ground, but the cost of exposure. In WWII, anti-tank guns, mines, and close air support were the “tank killers.” In the Cold War, ATGMs and attack helicopters were the terror. Today, loitering munitions and persistent ISR compress the timeline between “seen” and “hit.”

Historically, the counter is doctrinal as much as technical: dispersion, camouflage, deception, smoke, electronic warfare, better air defense, and combined arms at lower echelons. If tanks become less concentrated and more networked, that’s not obsolescence—it’s another doctrinal cycle.

From a “kit” perspective, I think the big shift is going to be what rides with armor units and what’s bolted onto the vehicles. The tank isn’t just a gun on tracks anymore—it’s going to be a sensor + counter-sensor platform.

If you’re looking at why tanks get clapped in videos, a lot of it is: poor situational awareness, operating without overwatch, and getting caught stationary. The practical fixes look like: organic drones per platoon, thermal optics that actually work in bad weather, better comms discipline, more smoke (including multispectral), and anti-drone protection that isn’t an afterthought.

“Obsolete” would imply infantry don’t need an armored, mobile, protected breaching tool. I don’t see that. I see tanks needing more supporting gear: EW vehicles, short-range air defense, recovery assets, and more dismount tools to keep drones and AT teams off them.

I’m not a tanker, but I’ve worked around armor in training and deployments. What people miss is how much a tank changes the behavior of everyone else on the battlefield. Even when it’s not firing, it’s pressure.

Tanks die when they get used wrong: unsupported, no recon, no infantry screen, no engineers, no plan for obstacles, and sitting still too long. In training you get hammered on “don’t skyline yourself,” “don’t bunch up,” “don’t stay in the same spot,” and “talk to your adjacent units.” The modern battlefield just punishes mistakes faster.

I don’t think tanks go away. I think units that can’t integrate drones/EW, proper security, and air defense will keep paying for it. The tank is still a tool—leaders and combined arms decide whether it’s a scalpel or a liability.

The “tanks are dead” crowd cherry-picks clips and ignores the boring reality: ground gets taken and held by protected firepower and bodies. A drone video doesn’t show the days of infantry stuck because there’s no armored punch.

Are tanks vulnerable? Obviously. So are IFVs, trucks, artillery, and command posts—everything is targetable when ISR is everywhere. The correct conclusion isn’t “delete tanks,” it’s “stop using tanks like it’s 1991.”

If a force can’t provide air defense, EW, engineers, and competent tactics, then sure—tanks will look obsolete. But that’s not the tank’s fault. That’s a competence and doctrine problem.

Tanks won’t disappear, but the “tank system” is being unbundled. A lot of what tanks used to do—recon by fire, spotting, overwatch—can be done by cheap drones and ground sensors now. That means tanks should spend less time exposed trying to find targets.

The future looks like: drones find/track, artillery or loitering munitions strike, and tanks move only when there’s a window to exploit or to physically secure key terrain. Also, autonomy will change protection: automated threat detection, cueing hard-kill APS, and rapid smoke deployment the moment a drone/ATGM is detected.

If you define “tank” as a manned, heavy tracked vehicle with a big gun, the manned part gets questioned first. I can imagine mixed formations: a few manned tanks as command/decision nodes plus unmanned heavy gun platforms that take the riskier positions.

“Obsolete” is unlikely because nothing else combines: protected mobility, direct-fire accuracy, shock effect, and the ability to take hits and keep fighting. But the classic MBT has to evolve in three areas: protection, signature management, and integration.

Protection: hard-kill APS is becoming mandatory, not optional. Add layered top protection, better belly protection vs mines, and active counter-UAS measures. Signature: thermal discipline, exhaust management, decoys, and rapid multi-spectral smoke.

Integration: tanks need organic ISR (small drones), tight comms with infantry/IFVs, and immediate access to engineers and short-range air defense. In Ukraine you can see what happens when any one of those is missing.

I expect fewer massed “tank charges” and more distributed armored teams. The gun still matters for direct fire, especially in urban or complex terrain where standoff missiles and drones can be blocked or jammed.

From a maritime perspective, “obsolete platform” arguments pop up every time a new threat gets headlines—torpedoes vs battleships, missiles vs surface ships, drones vs everything. What actually happens is navies redesign doctrine and add layers: sensors, decoys, point defense, and better networking.

Tanks are like surface combatants: expensive, visible, and valuable. That makes them priority targets. The answer isn’t to delete them; it’s to operate them with screening forces and defense in depth. For armor, that’s infantry screens, EW, air defense, engineers, and ISR.

Also worth noting: in limited wars, deterrence and political signaling matter. A capable armored force is still a very visible symbol of conventional power, like a carrier strike group—vulnerable, yes, but strategically relevant.

Air power affects whether tanks thrive or suffer. When one side has strong air superiority and good ISR, armor that moves in the open is in danger from aircraft, helos, and now drones. When air is contested and both sides have air defenses, tanks regain room to operate—because neither side can just loiter overhead freely.

I don’t think the tank goes obsolete; it just becomes more dependent on the air picture and air defense umbrella. If your SHORAD and EW are weak, your tanks become expensive targets. If you can deny the enemy persistent overhead eyes and keep attack aviation at bay, tanks can do what they’re built for.

Future seems like tighter integration: armored columns moving with counter-UAS, air defense, and their own drone reconnaissance to avoid being spotted first.

Not an expert on tank tech, but I’ll add a “people” angle: even if tanks evolve or shrink in number, armored and mechanized specialties won’t vanish. Militaries still need crews, maintainers, and leaders who understand combined arms.

For anyone reading this and thinking about a career: armor jobs are increasingly technical—sensors, comms, battlefield networks, and maintenance on complex systems. The future battlefield is more about integration than raw horsepower.

If you want to learn more without guessing from social media, look for official doctrine publications and training manuals from your country’s army or defense ministry—they give a better sense of where armored forces are headed.

SOF won’t replace tanks, but they absolutely shape how tanks survive. A lot of tank losses come from being found, fixed, and then hit—SOF-style recon, target designation, and sabotage missions contribute to that kill chain.

On the flip side, when armor is supported properly, it can enable raids and isolations by punching through obstacles and providing protected firepower near the objective. In many operations, SOF loves having conventional heavy assets available, even if they’re not “sexy.”

If tanks look more cautious in the future, it’s because the battlefield is full of observers—drones, scouts, signals intel. Tanks will need better counter-recon and tighter security, not a funeral.

Fieldcraft matters more than people admit. A lot of “tank is obsolete” content basically assumes vehicles are always visible and always emitting. In reality, camouflage, concealment, movement discipline, and deception still buy survivability.

Simple stuff scales up: hide from thermal, break up outlines, avoid predictable routes, manage light/noise, and don’t park in obvious spots. Add decoys and false positions and you can force the enemy to waste drones and munitions.

Tech keeps improving, but so do countermeasures. Tanks may need more support and more discipline around them, but the basics of not being detected first are still a huge part of staying alive.

Whether tanks become “obsolete” depends heavily on who is fighting, with what budgets, and for what objectives. Peer conflicts push high-end countermeasures (APS, EW, layered air defense). Smaller states and non-state actors lean on cheap drones and AT weapons to make heavy armor politically and financially costly.

We’re also seeing procurement debates: do you buy fewer exquisite MBTs, or more “good enough” platforms plus lots of drones, sensors, and munitions? Different countries will answer differently based on industry, terrain, and threat.

My take: tanks won’t vanish, but their share of the defense budget may be pressured unless they can prove they still deliver decisive effects under modern surveillance and precision strike conditions.

From an engineering/logistics viewpoint, tanks remain relevant because they solve a physical problem: crossing danger areas, breaching obstacles, and surviving direct fire while doing it. But they’re demanding.

If a force can’t sustain fuel, recovery, track maintenance, spare parts, and route clearance, tanks become stranded assets. Also, mobility is a whole system: bridges (MLC limits), roads, soft ground, minefields, and urban rubble. Engineers and recovery vehicles are what keep tanks from turning into stationary targets.

In future wars with pervasive drones, expect more emphasis on rapid obstacle reduction, lane marking under fire, smoke, and deception—engineering support will be a bigger part of “keeping tanks alive” than most armchair debates acknowledge.

I’m still learning this stuff, but I’m confused about one thing: if drones can hit the top of a tank, why wouldn’t armies just switch to lighter vehicles that are cheaper?

Is the main advantage that tanks can take small arms/fire and keep moving? Or is it the big gun for buildings and bunkers? Also, do active protection systems really stop drones or is that more for missiles?

In most plausible future scenarios, tanks don’t go obsolete—they become conditional assets whose value depends on the “transparency” of the battlefield. If both sides have persistent ISR and fast strike, heavy platforms must operate under concealment, deception, EW, and air defense to create local advantage.

Think in terms of windows: you suppress enemy sensors, jam links, create smoke, fix their shooters, then push armor to exploit quickly. Outside that window, tanks should be dispersed, hidden, and used sparingly.

Force structure wise, I could see fewer MBTs per brigade but more enablers: drones, counter-drone, EW, SHORAD, engineers, and precision fires. The tank remains the closer for certain missions, but it’s no longer the whole offense.

If anything becomes obsolete, it’s the assumption that the most dangerous job—driving the heaviest armor into the hottest zone—must be done by a human crew sitting inside it. Robotics will push us toward optionally manned or unmanned armored vehicles.

Picture a “manned command tank” staying slightly back while unmanned heavy platforms probe, breach, and draw fire, with sensor fusion feeding a shared picture. That reduces crew risk and lets designers change layouts (more armor up top, different ammo handling, modular mission packs).

So I don’t see “no more tanks.” I see “tanks plus robotic wingmen,” and the definition of a tank stretching into a family of armored systems rather than one iconic vehicle.
