Hollywood presents fighting war in this heroic way. After seeing enough videos of soldiers getting blown to bits by randomly passing drones, I think it’s more bleak than that. You likely are going to get killed in the least heroic way… lying in the dirt.
Based on these casualty numbers there is just about a 99% chance you will be killed or severely maimed. Unless you have a legitimate higher purpose for fighting, which I believe the Ukrainians do, it would be best to avoid it all together.
