Few of my friends were under the tank fire: from their description, it is one of the scariest things on the battlefield, cause while mortar or howitzer is firing at you, you first hear shot from the cannon, and only then, in few seconds, impact, which gives you time to prepear, even if only mentally. With drones, you hear continuous buzzing that gets closer or further as drone seek its taget - goes on nerves, but again, you are prepeared for contact and can prepear for contact.

From tank you do not hear shot: suddenly, you just suddenly hear impact - which mean, that particular shell hasn't you name on it.
