Download all wallpapers for ground forces

I was wondering if there is a way to easily download all available wallpapers of new vehicles like the one of the recent Leopard2A7V?

or the STRV: 2560x1440_strv_122b_plus_logo_f74ab6d3795355d60e2c375cbea049be.jpg

These are not available under Wallpapers - Media - War Thunder as far as I can tell.
