Rough, Tough and Ready (1945)

"The Screen's Newest Fighting Team Brings You A Screenful Of Thrills!"

The story is the old bromide about two brawling buddies, duking it out over the same girl, in this case pert Jo Matheson (Jean Rogers). Owen and Brad own a salvage company, but split up over Jo. Both separately sign up for the army, and both are reunited in the Pacific.
