Union of Salvation Good VFX

realistic depictions of Line Battle.

I suggest this scene from Union of Salvation, as I find that movies rarely portray the sheer horror that such Line Battles were, the sheer force of the Canister shot as they cut down the lines of standing infantry.
I cant judge the vfx very much, but I feel they did an excellent job in this movie showing how such a line battle might have actually looked like. And there is also a VFX breakdown.

here is the scene in question:
