Which of the weapons you mentioned has capability to occupy ground? I think Ukraine taught us that 2k soldiers in a factory area can delay a much more expensive army for months or until they run out of food/ammo. Russian needed a million infantry men to have a chance of occupying UKraine. Afghanistan collapsed by mere infantry in a few weeks, only because they could not move fast enough. If one wants to occupy and keep land in today’s nationalist states, swarming is still the most viable proposition.
