It is reasuring to know there are fervient citizens like you amongst the population of Rheinland, with good will and strenght to help those in need.
That being said, I'm afraid your goals would not be achieved in service of the Rheinland Militär, as you proclaim your goal to be the protection of the population and defense of Rheinland above all else. We're the spear, you wish to be the shield.
Therefore, Herr Detzen, I suggest you apply to the Rheinland Federal Police, which acts solely to protect the nation.
Alternatively, you're more than welcome as a member of the Rheinwehr in the secondary fleet, from which you may eventually join the primary, given time.
