You have to purchase the skill with runes (Mind tree). Level 1 gets you one reserve slot opened up, Level 2 gets you the second.
Then you can drag troops from your army to the reserve slot(s). Also, you can pick up wandering friendly troops which do not match your current army if you have a reserve slot open. If you keep "like" troops in your reserve, you can then refill the army ranks from those slots.
