From reading comments made by members of my Father’s WWII Battalion, most of the men who received minor wounds did not put in for the purple heart.
The attitude seemed to be that they knew someone who was much more seriously injured and sort of felt unworthy compared to their comrades. I specifically recall one who had a small piece of shrapnel removed from his face.
If it had been me, I certainly would have applied for one. If I met the standard, then I would get it.
