Ideas for a new drones

I had ideas for two to three new drones,y first one would be a flame thrower drone, it would have an flame thrower attached like the one with the gas, my second and third would be a drone attached with thermite or an impact grenade, it would also have a backpack but with like 5 backup drones because the drones would be a one time use, they would be like FPV drones which would choose automatically the target or that you as a player need to control it.

What do you think?
