UAVs and other modern ISR tools are great, but they are by no means a replacement for a recon vehicle. There are lots and lots of tasks that cannot be conducted by electronic/airborne ISR and still need boots on the ground. UAVs can’t and mark find creek crossings, can’t clear security zones, can’t deny enemy ISR, can’t secure FUPs, can’t guard flanks etc etc. Plus, airborne ISR is almost entirely useless when there is a significant enemy air defences. The future is not about replacing ground recon with airborne/electronic ISR, but with enabling ground recon with airborne/electronic ISR.
