Answer:
The horrors of war is something that is not well understood. You get to see men die, men you joked with, drank, had fights with. They are cut down by bullets, some step on mines and have half their bodies blown off, you're forced to shoot back at teenagers. The emotional trauma is incalculable. People are buried in parts, some have their charred bodies buried. A friend was once buried with just his limbs. The services are rushed or done in large numbers.
Peacetime funerals are markedly different. Your loved ones are clad in black, your body is buried in solemnity, hymns are sang, tears are shed, but above all, you're surrounded by people you love and love you, and your body is complete.
