Firstly I don't think anyone should be allowed to join the army until they're 25.
Secondly, I personally think you should only join the army if you fully follow your country's politics and truly believe in the direction your Country is going in. The training and discipline you learn in the army can be great but bear in mind that it's the military on the ground that have to do the dirty work that decision makers in office aren't prepared to do themselves.
