Reword rule “Health” so that it reads:

There exists a numerical statistic, called Health, that is tracked in the GNDT for Soldiers. New Soldiers start with 10 health. A soldier with 0 health is considered to be Dead, otherwise it is considered to be Alive. Other entities who might not be Soldiers may also have Health if the rule which defines them states how their Health is tracked.

Create a new sub-rule “Damage” under rule “Health”:

Whenever any entity that has a health statistic (for example, a Soldier) is said to take damage, their Health shall be reduced by an amount equal to the damage taken. If this would cause their Health to become lower than zero, it becomes zero instead.

Create a new sub-rule"Recovery” under rule “Health”:

As a weekly action, a living Soldier that has less than 10 Health may visit the Infirmary and set their Health to 10. If so done, that Soldier may not join any Skirmishes within 48 hours of visiting the Infirmary.
