Back in the days of the firing squads, they would only put a live round in one of the rifles. The rest got blanks.
And someone paying attention could feel the difference in felt recoil. Of course someone might be distracted by being a firing squad member? 
That's what I've always thought as well. Anyone who's fired more than a few rounds would be able to tell the difference. Maybe it's just a myth.
It's definitely true that some of the members of the firing squad get real bullets and the rest get blanks. I think that it might be more than one person who gets real bullets, though.
Yeah i would expect them to end up with PTSD.
It must be a really horrid job. OMG imagine
if something went wrong, and it didn't work...
I suppose if it is a lethal injection then it would be a doctor, is that
correct?
I think that doctors find that it's against their Hippocratic oath to administer lethal injections, but they will declare the inmate dead after the execution is finished. I think that sometimes the technicians find it difficult to find a suitable vein for the IV, especially if the inmate was an IV drug abuser. In some of these cases, I think that they get a doctor to help them start an IV.
For firing squad executions, I think that a doctor will find the inmate's heartbeat with a stethoscope and pin a white target over the person's heart for the firing squad to aim for, to lessen his suffering.
