In the modern day artillary, rotation of the earth is taken into account. Moreso from the standpoint of the earth is moving and over a 15-25 second time-of-flight that's important.
I have shot a round or so almost straight up. (You're on your own if you try this.) I have a good eye for angles and such and it hit right were I planned it - about 20 yards away. Not as unsafe as one might think, as we watched it go up and come down - 10 to 12 second time of flight.
On the other hand, decades ago, I tried shooting INTO the WIND. (Winter, Iowa) Shooting at about 60 degrees elevation the round landed well behind us. (The wind DOES blow in Iowa.)
