I was thinking of two opposite scenarios, and yeah.

1. You're in a fire fight, and shit's intense. So intense that you piss yourself. Next thing you know, a sniper fires at you, and just barely misses your head, and plants a nice one in your chest, or boob, or whatever. You look at your health. 38, and slowly... Dropping? What?

Face it, you're almost dead. This is war, soldiers bleed out all the time.

2. You're running towards the front lines, and you see enemies. You sight in with the rifle, take aim, fi-- Fall into a hole. You lose a quarter of your health, but... It's slowly rising. I guess minor injuries aren't permanent. You decide to wait till you're back 100%, and climb out.

Just saiyan, minor shit should be able to heal over time.

This way, soldiers can still make a stand without having to run back to the tent for health.

If none of you agree, then we should have our soldiers equipped with basic medical supplies, to both heal yourself and others-- Once per life.

Say you and your buddy are the only ones fighting at the front line, and he gets pegged hard. You look at him, and (just another idea, our soldiers' heath statuses should be displayed below their names) see that he's bleeding out, say, at 23%. You decide to heal him. Since soldiers can't carry tents with them, you only heal a fraction of health... 25%? Meh. Anyway, you heal him, and he's above percentage for healing, and he begins the healing process.

Backup then arrives.

tl;dr: Once health dips below a certain percentage, you begin to bleed out. If it's above a certain percentage, it slowly regenerates. OR Soldiers carry basic medical supplies, being able to either heal themselves or others once per life.

Whew.
