For example, for doctors, they have a contract to serve for a minimum of 16 years. If they kick out before or break off with us, they have to pay all the money back that we invested in them for their university and for them to become a specialized doctor--for example, someone who does heart surgery or something else. This is what is in their contract. The minimum time before they can get out of the army is 16 years, and then they can say, okay, I'm looking for a second career, and they have the chance to do so because they are well specialized and well trained to do so.
Afterwards, if someone is getting out, we always have someone as a backup who then can fill their shoes.
