One way is to focus on the soldier's motivation. For example, if the motivation is revenge, say his family was killed by an enemy force. He then devotes his life to getting strong enough to fight back. Another way is to consider their upbringing. A soldier raised in a military family might have different values and experiences compared to one from a civilian family.
You can start with the setting where the soldier grew up. If it was a war - torn region, he might have seen a lot of destruction from a young age, which made him determined to end the chaos. Also, think about the relationships in his life. Maybe he had a mentor in the military who inspired him to be better. This relationship can be a crucial part of his back story.
To create an interesting soldier back story, you need to give the character depth. Consider his fears and weaknesses. For instance, he could be afraid of heights but has to overcome this fear during parachute training. You can also add some unexpected twists. Like he was supposed to be a doctor but chose to be a soldier after a life - changing event. This combination of elements will make the back story more engaging.
