Spawning SPAA doesnt waranty a kill, there is some boring time where we just look at the sky.
To help the gameplay and bring more team play, it should be interesting to give them some scout drone to help team while the sky is clear.
Scout drone can be carried by any vehicles IRL so it doesnt kill any immersion.
Some High tier SPAA already have the scounting ability, so one ability more is not problematic.
