I know on a blog with the Gra in the title it is hard to understand why I would put being in the Armed Forces as good thing. While being in the Armed Forces could cramp your ability to keep all the Mitzvot with all the details. 

Still getting married takes precedence. If a Litvak (Lithuanian) Rosh yeshiva's daughter is a possibility I figure then those people  are not looking at this blog anyway, and that would have happened already.  So obviously you were by-passed. 


 And the religious world is a disaster zone when it comes to shiduchim. [It is  a cheat and a racket for the benefit of the few at the expense of the many  baal teshuvas.]
The main thing there is the fraud and scams. This is besides the fact that the religious world outside the yeshivas is simply a fake religion. It pretends to keep Torah, but worships their human gurus. 

So to be man, it seems to me there is little choice but to  do the Armed Forces thing. [Unless something clicks in university.]

War is justifiable if it is to protect one's home.
