Welcome, from another noob Commander.
Try STA 1.2 first, then if you like it send the team a donation and see all the work they have put in since 2016!
http://stasf2008.forumotion.com/t6-stasteel-fury-1-2http://stasf2008.forumotion.com/t805-stasteel-tank-add-on-3-3-steel-furyI have tried the 1.2 version and it does work with widescreen and GMP 1.x.
It is quite pain free to get working compared with trying to do all of it manually. Just follow the 1.2 instructions and have fun.
Driving without stalling and shooting on target is taking some work!
