The '(Combat Patrol)' units from the Malden DLC does not show an image preview anymore.
All units have an image preview in the Eden editor, but unfortunately these ones are bugged.

The game gives you this error message when you hover above the units with your cursor:
Cannot load texture a3∖editorpreviews_f_argo∖data∖cfgvehicles/b_patrol_soldier_a_f.jpg.
