I think its important, as you point out very well, to remember that what is most effective in Ukraine today doesn’t need to be what “would have been” most effective if Ukraine had access to it.
You point this out for artillery, where FPV drones appear to have largely replaced heavy artillery. However, can partly be explained from lack of guns/shells.
I think the same may be true for heavy tanks. Neither Ukraine or russia seem to be using a lot of heavy tanks, however I think that may in part be explained by lacks in breaching equipment, and lacks in mobile frontline air defence. I don’t think “armoured fist” assaults led by dozens of heavy MBT’s are necessarily outdated, but I think Ukraine lacks the equipment to pull them off.
Exactly, and in addition to artillery support, we see in Ukraine today that massive amounts of breaching equipment (mine clearing vehicles, portable armoured bridges, etc.) are required. A mine field is capable of stopping pretty much any armoured assault if they lack mine clearing equipment (as we’ve repeatedly seen). However, it was clearly shown in Iraq what a large number of armoured vehicles with explosive mine clearing charges can do.
It’s not enough to give Ukraine tanks. If they’re going to succeed with an armoured push of the kind they tried through Robotyne, they need dozens of mine clearing vehicles, man-portable mine clearing equipment, and mobile frontline AA as well.
One major hurdle that needs to be overcome is a way to defend such armour against drones. I’m guessing that some kind of light and cheap AA is already pretty far along in development.
