Impact/droppable mortar charges for drones.
In games like ARMA Reforger, Squad, etc, all have anti-infantry drones, this feels like a natural evolution of the current use of C4 on drones.
For example; if you are stuck inside of a building while the enemy team is capturing the point, you can deploy the anti-infantry drone to directly combat them without getting into harms way. Some downsides of the drone could be; lower range (Ie; A range of about 30% the current drone), limited mobility, and being one time use (per life).
Along with this, there are two main ways to implement it;
A: Create a entirely new drone for another class
B: Make a mortar shell/RPG cargo piece
I feel that this would be a great feature that can change the dynamics of the many scenarios.
