Enlarging the picture I see one on each of the first three guys. Since we were talking about the carbine I wronly thight me meant an M3 carbine not an M3 trench knife.

Three pictured, that leaves 2,590,244 others made during that time to find.

I can understand your confusion, Jim. I apologise, but as first aid pouches had already been mentioned I felt it okay to go slightly off topic. As a fan of the M1icon Carbine, M4 bayonet, and the M3 knife I find it very interesting to see any of them in the same picture. To see three is a bonus.
