So then this "white army in heaven" is simply consisting of ordinary christians who are saved and whitewashed in the blood of the lamb, more cowards than real warriors, the normal peaceful people with peaceful mind preaching the white gospel and presented here as victorious coureagous winners of a battle. Projection in its best form. And again not a real divine judgment or killing of enemies but the gospel is fighting and victouriousy winning.
Like a war but not real war.... it's a spiritual war.. the preaching work is biblically called a spiritual "white war " all of you sitting on white horses riding on command of the white king against invisible evil fighting in the world putting on the full armor of God, Ephesians 6, combined with white linen then if so, but never destructing something but only healing the hearts.bizarre to call and project it as "war", but hey the gospel "wins" how comforting. You are on the winner side.
