You are:
Big Wind, the oil well fire tank.
I have a complicated origin.
My father is Omani Hungarian, while mother is Russian.
From the article: "This unique firefighting tank, which is fondly called "Big Wind" by some and "Windy" by others, has its own multicultural history. The tank is Russian, the owner is the Arab-owned Hungarian company MB Drilling, a division of the MB Group of Oman, and it was created in 1991 in a town 50 miles southeast of Budapest."
I have three engines, only one for driving.
Two are for blowing air/water onto the oil well fire.
What makes me was in the army, but now I fight against a different enemy.
This thing is a tank!
I blow wind and water.
With those two extra engines.
I blow out devil's flame like blowing out candles.
Oil well fires are nasty stuff!
My first job done in a greasy, scorching inferno in a desert, alongside a gulf.

I was under one year old, and showed up in a documentary that almost won an Academy Award.
