Military analysts will watch these engagements closely. Who needs dedicated CAS anymore when cheap, reliable drones can inflict major casualties on even somewhat organized armies? It's not a big deal if the drones get shot down, Turkey can just produce more. All it takes is a one good hit to get a major return on investment.
Would love to see how Turkey fairs with this strategy in Libya if they do confront Haftar (although, I'm not sure if they can project air power the same way in Libya because of greater distance)
They are also extremely cheep to operate and have more than 24 hours endurance. They can stay over the battle field 24/7,the cost effectiveness of flying a Bayraktar TB2 instead of f16 for 24 hours is enormous. Turkey has a fleet of around 100 Bayraktar TB2 and still increasing. You can also use drones to lure in enemy aircraft to ambushes during a war time. Forces will have to make a decision on whether to sent interceptors to shoot down drones or fire costly Surface to air missiles to shoot down drone. Modern armies will have to build cheep weapons that can shoot down drones, or it will disrupt the entire battlefield.
During India pak tensions last year, first Pakistani drone was shot down with spider and rest 3-4 were shot down by Sukhois with air to air missiles. Sending sukhois to shoot down a drone which is flying close to Pakistan border is dangerous and if you fire spider, enemy will know the location of your air defense systems. Its a really tricky situation. Looks like Indian military decided against using ground based air defense systems to engage drones and are dispatching fighters to shoot them down.
