The point of changing the climate is very deeply involved into Army! Just remember why Germans lost on the East front! And also, for example the wheet! It is the most sensitive on climate changing, like all those important plants for living, changing of climate would destroy it, correct? Than enemy, if he is under sanctions, won't have anything to eat, correct? And he must surrender! Everything is in food, and water..........
Than making bad weather! That's doing bad on people's morale!
And many other things...................
But it is the certainly the biggest helper on the battlefield!
When enemy is attacking, make bad weather!
When You are attacking, make good weather!
And just remember how it's worsing the situation, when You are attacking on the rain, with lotta mud, not seeing anything! And than You are tired, and enemy can kill so easy........................
