Deadly Cannons

Soldier!
Very simple rules!
There is group of cannons
That you need with them scrow
You don't have to hurry
But you have to know
Deadly cannons can kill you
I think this worth to know
So pay attention to this
Very simple rules
And look on helth points
And ammunition too
And don't forgiet of fuel
Becouse you should know
That tank without a fuel
Is just a piece of junk
