The dio will show a German flamethrower halftrack and some infantry slowly advancing across a field towards an unshown town controlled by guerillas

Edited it to make the markings easier to see.
The black thing’ll be the halftrack. The markings a little oversized.
Blue X will be a kneeling sniper leaning the rifle against a small tree or post as he watches the town.
Red and Green Xs will be men slowly walking along with the halftrack with weapons at the ready.
The corner with the yellow thing I’m not sure about. I was thinking of making it the corner of a small shed with an armed guerilla hiding in it but I’m not sure how well that would fit into the scene.
What do you guys think?
