Military Internship - Pro&Cons for an S&T Career

Hi everybody, 

I'm actually an undergrad in France (PSL - Dauphine) and between the two years of graduate, we have a gap year where we can do two off-cycle internships. I just have the possibility to have a formation with the french army dedicated to students like me, but the problem is that I will only have one off-cycle experience after my graduate. Do you think that this could seriously hamper my chances of getting into a S&T job? Or, on the contrary, do you think that this is a good thing in view of the similarity of all the files. 

Thank you for all your answers
