Do soldiers go to heaven?

Those who trust Jesus Christ for salvation do. Those who trust their own efforts don't.

Nope.

No one goes to Heaven.

You mean as opposed to the one's who endanger their country? Which one's are those?

Being a soldier does not interfere in the path to Heaven. There are many saints which have been soldiers.

I don't know, and there is no evidence one way or another.

Why would they go to heaven ?

killing in a just war is exempt from murder.

the saved ones do.

The wicked spirit persons, aka angels get humans to fight their numerous wars and the get humans to kill other humans and do horrible things to other humans. Some feel they are doing the right thing and only God knows their heart. So we are not the judge but I think those who do not go to war and kill others would do better in the eyes of God.

It seems that the "gods" have many soldiers so protecting those sheep who are incapable of doing so themselves is a noble and blessed occupation.
