**I'd guess the time frame on this one to be 1960's or 70's.**

["If the Red Slayer"](http://www.isfdb.org/cgi-bin/title.cgi?71156), a short story by [Robert Sheckley](https://en.wikipedia.org/wiki/Robert_Sheckley), first published in [*Amazing Science Fiction Stories*, July 1959](http://www.isfdb.org/cgi-bin/pl.cgi?56423+c). The title is from the poem ["Brahma"](https://www.poetryfoundation.org/poems-and-poets/poems/detail/45868) by [Ralph Waldo Emerson](https://en.wikipedia.org/wiki/Ralph_Waldo_Emerson).

**The story is set on Earth, and centers around a soldier who has been killed several times in a war that has dragged on for years between rival powers. The soldier is American (IIRC), and the enemy is probably one of the communist powers of that era. The war has gone on so long, and been so bloody, that there simply weren't enough fresh recruits to replace losses.*

At the beginning of the story, the limit is three resurrections, and the protagonist is complaining because he has accidentally been resurrected for the fourth time

> "But our enemies outnumbered us," the kindly old sarge said.  
<br>"They still do. All those millions and millions of Russians and Chinese! We had to have more fighting men. We had to at least hold our own. That's why the medics started reviving the dead."  
<br>"I know all this. Look, Sarge, I want us to win. I want it bad. I've been a good soldier. But I've been killed three times, and—"  
<br>"The trouble is," the sarge said, "the Reds are reviving their dead, too. The struggle for manpower in the front lines is crucial *right now*. The next few months will tell the tale, one way or the other. So why not forget about all this? The next time you're killed, I can promise you'll be left alone. So let's overlook it this time."

**He notes that the nature of needing to get people back into the fight as quickly as possible has meant certain short cuts in the operating room. One of his arms is a little longer than the other after being re-attached. His ears don't quite line up, etc.**

> The brahmins had done a pretty good job on me. Not as good as they did in the first years of the war, of course. The skin grafts were sloppier now, and I felt a little scrambled inside. Also my right arm was about two inches longer than the left; bad joiner-work. Still, it was a pretty good job.

**He then finds out that the demands of the war have led to retroactively increase the number of times you have to fall in battle before being allowed to finally die.**

> "Private," he said, "I'm sorry about this, but new orders have been issued. The Reds have increased their rebirth rate, and we have to match them. The standing order now is six revivals before retirement."  
<br>"But that order hadn't been issued at the time I was killed."  
<br>"It's retroactive," he said. "You have two deaths to go. Good-bye and good luck, Private."

**The final death comes when the protagonist is shot in the head during a battle. An explosive-tipped bullet, IIRC. His last thought was that he finally gets to die.**

> I felt the explosive bullet slam into my forehead. There was the tiniest fraction of a second in which I could feel my brains boiling out, and I knew I was safe this time. The brahmins couldn't do anything about serious head injuries, and mine was really serious.

** It's explained a new technique has been developed that can "unscramble" traumatic head injuries, and that a head shot is no longer a permanent death.**

> "At last medical science can treat serious head injuries," the brahmin told me. "Or any other kind of injury. We can bring any man back now, just as long as we can collect seventy percent of his pieces and feed them to the de-scrambler. This is really going to cut down our losses. It may turn the tide of the whole war!"

**The story closes with the protagonist going back to his duties, weary and thinking about the time when he'll finally get to die for good.**

> I nodded, and in a little while I was given my clothes and sent back to the front. Things have quieted down now, and I must admit it's kind of pleasant to be alive. Still, I think I've had all I want of it.  
<br>Now I've got just one more death to go before I'll have my six.  
<br>If they don't change the orders again.
