How to fight wildfire?

I recently read this case of wildfire happening in a country.Then it came across to me an idea,why not use water-bombs.I remember playing with balloons filled with water when I was young.

Can use water as a payload,then this hydrabomb can be guided to a specific destination like a forest fire etc.A timer can be added,such that the water can be released at a determined time.

You watched the movie Ironman?,where the missile "Jericho" was introduced by the character Tony Stark,the missile has smaller missile encapsulated in 1 missile.

Same concept here,or the payload can be nitrogen/compressed carbon dioxide?

Just a penny for my thoughts.
