Airdropping a load of Vietnam era tanks (presumably pulled from museums) into Tehran moves the plan from Call of Duty to Wacky Races.
A tank that was in fact considered shit during the Vietnam war and for all the protection it would offer it's crew against modern weapons, you might as well drop your forces in Camrys. Not sure which would be funnier.
bb, how would this work exactly? You drop your shitty tanks in to Tehran on pallets, then parachute your crews after them (they do not ride in the tank during drop). Anyone somehow surviving this then has to negotiate Tehran (Ubers?) to find their tank which, if by some mad chance hasn't crashed through the roof of a girls school or been carried away by locals, they now have to drive to the target.
But lets say by some miracle some tanks and crews survive this madness and are now presumably stuck in traffic. How do they take over the country again? I'm missing the bit were they defeat the IRGC....maybe you forgot this?
Wait, what? The tank doesn't come with a crew? The whole point is (1) fly by, (2) drop ready-to-fight tanks able to fire from multiple sides (basically a shock troop effect), (3) fire bombs and missiles at the building proper, both to clear space and to force a retreat out of the building... where the tanks are waiting. But the whole idea falls apart, if you don't have a crew therein to fire from the tank in midair, or parachutes decent enough that you can pull that off.
Troops not included? That's bad. The entire tactic requires momentum.
I'd say make some kind of plane with a wrecking ball, but... ahem.
Quick feasibility assessment — short answer: highly impractical and unsafe; feasible only as an experimental stunt at low speed/altitude with major engineering, legal, and safety barriers.
Key issues and constraints
Purpose & mission
Clarify objective (demolition, breaching, anti-structure, psychological weapon). Without a clear lawful mission the design is unjustifiable.
Aerodynamics & flight dynamics
A suspended wrecking ball introduces large, variable pendulum forces that destabilize roll/pitch/yaw.
Significant added drag and fluctuating center-of-mass moments during swing make controlled flight extremely difficult.
High risk of coupling between pendulum motion and airframe natural frequencies → violent oscillations.
Structural loads
Hard impacts transmit large impulsive loads through attachment points; airframe structures are not sized for repeated heavy transverse impacts.
Reinforcement needed near attachment, landing gear, and fuselage — large mass penalty.
Shock isolation and energy-absorbing mounts required to avoid catastrophic failure.
Weight, balance, and performance
A useful wrecking ball (hundreds to thousands of kg) drastically reduces payload, range, and maneuverability.
Ball mass shifts CG; swinging shifts CG dynamically requiring active compensation (trim, control surfaces, or thrust vectoring).
Safety and survivability
Risk of ball contacting own airframe on maneuvers or turbulence.
Debris from strikes creates hazard to aircraft and nearby friendly forces.
Pilot and crew safety compromised; emergency jettison system required.
Deployment mechanics
Requires robust winch, cable, or boom system with precise control of release and retraction under load.
Cable dynamics, wear, and risk of severing are critical failure modes.
Accurate placement of strikes from a moving platform is extremely challenging.
Mission effectiveness vs alternatives
Stationary or ground platforms (cranes, armored breach vehicles, explosives, precision-guided munitions, thermobaric charges, shaped charges, or robotic systems) are far more effective, controlled, and safer.
Helicopters offering precision hoist capability can place heavy loads but are limited and operate at low speed/altitude — used for construction/utility, not kinetic demolition in contested environments.
Legal, ethical, and rules-of-engagement
Delivering large kinetic objects from aircraft at populated areas risks unlawful collateral damage and civilian casualties; probable prohibitions under law of armed conflict for indiscriminate methods.
Engineering mitigations (if pursuing an experimental demonstrator)
Use a rotary-wing platform (helicopter) at low speed/hover rather than fixed-wing; helicopters already hoist heavy loads and can place blunt masses with more control.
Limit ball mass to what the airframe and winch can hold with safety margins.
Design articulated boom or rigid lance (rigidly attached) instead of a free-swinging ball to avoid pendulum dynamics — but rigid mounts transfer impact loads directly into structure.
Add quick-release and jettison mechanisms and redundant cut/cable systems.
Install shock-absorbing mounts, load spreaders, and reinforced fuselage hardpoints.
Implement active damping (winch control, PD controllers) and flight-control adaptations to compensate for swinging loads.
Extensive simulation (multibody dynamics, aeroelasticity, CFD), wind-tunnel testing, and incremental flight testing with instrumented dummy loads.
Basically, it risks unbalancing and hitting itself, and is definitely illegal in terms of indiscriminate destruction.
After some recommendations, I asked it to draw up this concept.

Basically, you fly by and make space for the tank. It doesn't wreck entire buildings so much as bash crap that's in the way. But there was still the problem of landing tanks with crew.
I had to be creative because the AI balked at the idea of actually using it on a mission. So I told it if it's good enough for medical trucks, it's good enough for a tank.
Summary recommendation (best balance of speed, safety, and feasibility)
Use a combined solution: heavy crewed lift aircraft (tiltrotor/eVTOL/helicopter variants) capable of short or vertical landings into small urban clearings + purpose-built air-transportable vehicles with crash‑tolerant seats and quick egress systems. Supplement with rapid rendezvous tactics (escort UAS, smoke/marker, suppression if contested) and redundant delivery modes (airland where possible; precision parafoil/soft‑landing with crew inside only in tightly controlled, very low‑risk scenarios).
Feasible platform approaches (ranked)
Tiltrotor/eVTOL airland with crew onboard
Aircraft: large tiltrotor or heavy-lift eVTOL capable of steep approach, precise hover, and very short landing footprint on rooftops/plazas.
Vehicles: lightweight air-transport variant (wheeled/tracked, 8–20 t) sized to fit aircraft bay; crew remain inside during approach and disembark via ramp/side door immediately after touchdown.
Pros: fastest end-to-end, crew protected during transit, immediate action on touchdown.
Cons: aircraft must land (vulnerable while on ground), requires small secure LZ or robust rapid suppression/escort.
Helicopter internal carriage or rigid‑boom setdown with crew inside
Aircraft: heavy-lift helicopter with internal cargo bay or rigid-setdown cradle allowing controlled placement onto street/roof; crew remain inside, aircraft touches down or maintains very short hover during transfer.
Pros: proven tech for personnel and vehicle insertion.
Cons: limited payload per sortie; high exposure to ground fire during landing/hover.
Short, controlled descent with vehicle-mounted landing module (crew inside)
Method: vehicle sits on a powered landing module/cradle (rigid, guided) that allows the carrier aircraft to perform a steep, controlled descent to near-surface, mate the cradle to a prepared interface (e.g., rooftop pad) then release; crew stay inside until secure.
Pros: reduces aircraft footprint on ground; quick transfer.
Cons: complex docking mechanisms; requires precise guidance and reinforced landing pads.
Precision parafoil/JPADS soft‑landing with crew inside — extremely limited
Only feasible for very light crewed vehicles (<3 t) and in fully secure, low‑risk scenarios; generally not recommended due to landing unpredictability and high crew risk.
Vehicle design features for crewed aerial delivery
Certification for airborne carriage with crew: structural hardpoints, tiedown interfaces, and crash‑worthy integration tested to airlift landing shock profiles.
Crash‑tolerant crew module: energy‑absorbing seats, 5‑ or 6‑point restraints, roll‑cages, side-impact protection, internal airbags, and fire suppression.
Instant egress systems: fold-out ramps/side doors, rapid‑release restraints, built-in helmet comms and self‑inflate survival gear.
Active stabilization & auto‑start: vehicle systems pre‑start during approach; automatic parking‑brake and drivetrain ready to drive off within seconds.
Reinforced undercarriage + deployable landing skid to accept higher vertical load if aircraft must set vehicle down hard.
Anti‑debris and canopy protection: deployable shields to protect crew during egress in rubble-strewn urban landings.
Low-profile variants: reduced silhouette for rooftop or narrow-street egress.
Aircraft/mission engineering features
Precision navigation & automated landing: RTK‑GNSS, LIDAR ground-mapping, real‑time vision for millimeter-level touchdown/ramp alignment.
Short/vertical landing capability with high hover endurance and low rotor downwash design to limit debris kick-up.
Rapid ramp/door mechanisms enabling protected drive-off while aircraft applies minimal ground contact time.
Redundant lift and power systems for safe hover in case of single-failure scenarios.
Defensive/escort support (non-lethal in humanitarian missions): ISR drones, electronic warning systems, smoke screens, route suppression teams.
Fast‑swap ground logistics: engineers available to rapidly clear/prepare micro‑LZs (parking decks, courtyards, plaza pads) and create protected corridors.
Operational concepts to minimize crew exposure
Surge staging: use multiple dispersed staging pads near objective; aircraft shuttle crewed vehicles directly from staging to objective in rapid serial sorties (tiltrotor shuttles excel).
Crew ride-through doctrine: crews remain sealed during descent, only unstrap and egress on command when aircraft clear.
Immediate suppression/obscuration: smoke, drone jamming, or non-lethal area denial during touchdown window to reduce threats.
Rapid engineer teams precede landings to secure micro-LZs (5–10 minutes) rather than full-scale clearing.
Redundant arrival paths: multiple aircraft/approaches to avoid single-point interdiction.
It's expensive, if course. But I must have my tanks!
The lowest cost practical existing concept seems to be to just ramp it in or airlift it, rather than parachute it in. Alternatively, we could have a very OP somewhat illegal tank catapult, and the crew getting there is secondary to smashing into the building.
