That is actually a very meaningful order. I had to check, did they mean launchers or batteries. Looks like 17 batteries. That's pretty big, IRIS-T is very modern kit.
https://en.wikipedia.org/wiki/IRIS-T
Each system has 3 launchers capable of firing 8 missiles each, and 1 command/radar module per system.
These are spread out, and the command module can track 24 missiles at once!!!
Although these are not long range, they are very maneuverable, and although I'm not an expert, I'll risk the guess that they are perfekt against drones, and very good against missiles too, as long as they are not hyper sonic.
