From Ukraine to Iran, David is fending off Goliath in modern wars

Matthew Savill, the director of military sciences at Rusi, said if China were to invade Taiwan, the Taiwanese would make use of massed cheap drones as part of what he described as a “porcupine defence”...“If they [Chinese forces] can get ashore in large numbers, that hugely swings their chances of mounting a successful invasion. An asymmetric approach could be to conduct a long guerrilla campaign once they were ashore, rather than try to hold off the initial invasion. But that would be betting on the ability to bleed occupying forces and to outlast a Chinese political commitment to retain control,” he said.
