My boys (10 & 6) both want to be Marines - well they're undecided between Marines and Air Force. Yes the idea of deployment is scary but I will always support their decisions.
If they're dead set on the military I will make a plea for the Air Force as combat is less likely in this branch and the pay grade and educational opportunities are much greater in the Air Force. I don't have girls but women do get up to 3 years of paid maternity leave when they have a child - this is new... (contracted time must be made up after maternity leave)
My mother is an Air Force Veteran I have an uncle who is a Marine Veteran
One cousin who is in the Air Force- currently stationed in Germany (was able to bring her family with her)
One cousin who is in the Army that just came back from being stationed in S. Korea
And one cousin who is Retired from the Army.
My boys have talked to them about serving and the hard work and sacrifices that are made. They still want to do it though. They've stated if they don't go to the military they want to be Police officers (also have 3 of them in my family) or aspire to work for the FBI, (also have one cousin who works for them)
The youngest wants to get into Architecture and or Civil Engineering and the oldest into the Science field (hopes for NASA) if they go the Military route.
Of course they're so young that these ideals will change and as much as my oldest likes to argue I see a future for him as a lawyer lol
Maybe it's because they're surrounded by these amazing people in my family that they aspire to be like them. They understand the sacrifices to a certain degree and despite all this they still think it's what they want to do (for now)
I've got a long way to go.
You're daughter is older and arguing with her on what she should do with her life is only going to push her further to make that choice and may cause a rift between the two of you or she may leave you out of her decision and sign a contract that she doesn't really understand once she's of age.
Sit her down and ask her why she want to join the military and what her career goal within the military is- go with her to get informed on her choices and options, explore other branches and the types of contracts being offered, what the expectations of work within the military are and what she plans to do once she enters civilian life after the military.
Maybe once it becomes real she might change her mind.
Don't make her feel like she doesn't have a choice if she doesn't want to go to veterinary school there's hundreds of other choices she could be passionate about.
Good luck.
