Some people may think that, but the reality is totally different. If you as some Islamic migrant had passed all of the language basic requirements (B1), that’s not going to be enough real proficiency for a military slot (you will need B2 and possibly even C1). If you can comprehend and operate at that level of B2/C1...why in the world would you limit yourself to being a poorly-paid German Army guy?
As for the intelligence tests....if you wiggled around and found some easier method to allow them entry....then you’d have to go and accept marginal German citizens (with a poor educational situation) to take and pass the same tests. There’s zero interest in getting a dumbed-down group of recruits (even if they were Germans themselves).
A lot of this issue is that once they went to the volunteer Army...they had to pressed hard to pay a more realistic salary, and that has barely occurred. Generally, in the first year...your salary per month is 1,950 Euro (before taxation). Taxes and deductions take out near 40-percent of that. If you make it to corporal...your salary goes up to 2,200 Euro a month.
Based on what I’ve seen the past decade...a fair number of German recruits will come in....do three to five years and get out because salary levels tend to work better outside of the military, and by that point, they have a certification or two for job-skills.
If you follow the German military news....there’s almost monthly some new logistical scandal that has developed and military folks are standing there and shaking their heads because so many tanks, aircraft, or ships....that are ‘hanger-queens’.
It doesn’t need to be that complicated. They will simply engage in systematic fraud to make the unqualified qualified, with the same political goal-seeking mentality that got Hogg into Harvard. The end is all that matters to these people and no rule will stand in their way.
