While true, the real reason FMJs are used and not SPs or HPs or other expanding bullets, is because of military strategy and logistics. A wounded enemy needing enemy care, is far more resource consuming than a dead body.

It is funny to think, that while grenades, mines, anti personal artillery and other horrendous weapons causing "horrific wounds" as well are not considered cruel, expanding bullets are "too cruel" to be used.

If being captured with expanding ammo causes the POW to be "adversely" treated by his captors, I wonder if any other sort of weapon also gets a similar result? Serrated bayonets?
