The lowest end of possibility is this dismountable tank and pump unit used in the US Army FMTV trailer fleet.

I think the 7,500-gallon petroleum tank semitrailer is the most likely for that military aid line as semi-tractor connections are universal and Ukraine has access to Semi-tractors in the European Union militaries & economy to pull them.
The next several weeks will tell

...which we will see lines of them in the Ukrainian counter attack logistical trains.
Ukraine's 'big cats' will prowl on megatons of diesel fuel delivered by these trailers.
This map of 124 Russian railway electric traction stations and the 40K OWA drone fired in 2025 demonstrates the political-military leadership failure of the Zelinskyy government.
Like Stalin's failed winter 1941-1942 counter offensives against Nazi Army Group Center,
...Ukraine is penny packing OWA drones everywhere to no great effect based on which military "Union" faction was last in the room with President Zelenskyy before a decision
Even Ukraine's vaunted oil offensive is a bare plurality of total drone strikes 2/
The latest @RyanO_ChosenCoy thread detailing the bureaucratic issues of Ukraine's military in targeting Russian logistics makes clear Ukraine's military has inter-service and intra-service union/factional disputes that are positively American in scale.
If the target of a US "rapid strike" was either the Kharg Island oil export facility or Iran's banking/financial system with a combination of explosives and non-nuclear electromagnetic pulse munitions, the Mullahs will fall.
There are two real courses of action (COA) for an American air campaign if Regime Change is the goal.
The Schwerpunkt - political center of gravity - of the Mullah regime is its ability to pay for the use Regime Security Forces & foreign hired mercenaries.
This is one of the 3 major strategic mistakes of the Zelenskyy Government.⬇️
Putin has shown better, more consistent, and more effective leadership in the strategic bombing of Ukrainian electrical infrastructure than Zelinskyy has in striking Russia's railways.
Russia remains uniquely vulnerable to a focused drone strike campaign on it's electrical railway traction step down transformers.
Zelenskyy's leadership not only ignored hitting that unique Russian vulnerability since Feb. 2022.

To give you an idea of the abject political-military failure of the Zelenskyy government in this regard one has to look at the industrial supply chain for those traction substations.
The Soviet Union had two major transformer factories: Tolyatti and Zaporozhye.

The predominant effect of a 1.4 million rial to the dollar hyperinflation combined with Regime Security Force public lockdown is the Iranian lower class has been set up to starve.
The lower class cannot go to work to get money to buy food.
We really need to talk about the huge opportunity that Mullah financial corruption has given the Trump Administration to crash Iran's financial system with E-bombs, AKA non-nuclear electromagnetic pulse.
Wiping the financial records of failing Mullah banks in a revolution...
What jumped out for me about @shanaka86 substack article was the implications of secure digital text communications for the Maoist model of Revolutionary warfare.
See the @grok summary of Mao's 4-level revolutionary model below. ⬇️

Maoist Level 1 & 2 warfare has never had the secure digital text communications Starlink provides.
This means a whole heck of a lot and shoots decades of counter-insurgency doctrine about controlling/blocking guerilla communications in the head.
