Yes army service is a very serious issue all Turkish men must do. Losing citizenship takes a long time. I dont how many years they wait but they wait many years. During this long wait if the person comes back he will get arrested and will directly send to military service.
These kind men will be not very welcome in the army. They will have a harder time.

The health issue is too detailed. If you have some surgeries which prevent you to do sports properly you still will join the army but wont do the exercises.

You must have a serious illness. I think homosexuals are not accepted either.

Greetings,
there are two different verbs:

1. değişmek:
to become a different person
to become different
to change personality

2. değiştirmek:
to exchange with something else,
to change something, (the car, the text, the room or even myself)
to alter,
to replace,


Lets have a lok on the first one:
1. değişmek : to become different

değiş: verb stem
(become different)

değiş+ecek: verb stem + future tense
(will become different)
Example:
Bilgisayarlar değişecek.
Computers will change.

Saatler değişecek.
Hours will change.

Hava sıcaklığı değişecek.
The weather degree will change.

There are no personal suffixes on these exapmles and it wouldnt be suitable to add personal suffixes here. When they are added the meaining changes to "change personallity".

Some people incorrectly might say:
"Giysilerimi değişeceğim." but it should be,
""Giysilerimi değiştireceğim.", I will change my clothes.

değiş+ecek+im: değişeceğim : (consonant mutation k > ğ )
verb stem + future tense + personal suffix for 1.st singular
(I will be different, I will change)

Now the second one:
2. değiştirmek: to exchange with something else

değiştir: verb stem
(change something, exchange, alter)

değiştir+ecek: verb stem + future tense
(will change, exchange or alter)

değiştir+ecek+im: değiştireceğim : (consonant mutation k>ğ

verb stem + future tense + personal suffix for 1.st singular
(I will change something ,I will exchange something, I will alter something)


Now lets correct your sentences:

I cant check now the original text but your Turkish translation looks very good to me. Just a tiny improvment maybe:

"Bir manzarın güzelliği onun hüznünde yatar."

Education comes first before military service. I was 24 when I went to the army.
As long as he is a student in any university he will continue the study. Postgraduate studies also count when delaying the military service. There is a age limit though. I think it is 33 maximum.

The standart duty is 15 months. I think there is permission for 30 days off which doesnt count to 15 months. First month you cant have any holiday.

Men with a 4 years university degree can make 12 months (yedek subay) as a medium ranked military officer (lieutenant) with a good monthly sallary. They dont have to stay inside premises all day. They start the job in the morning and finish in the evening. This is quite comfortable. Or they can make a shorter duty of 6 months (kısa dönem) as a normal soldier (sergeant) without a sallary and cant quit premises any time except on weekends with permission.

Hi folks,
I have just removed the other topic upon request of originator. Accidents can happen. Need to worry about these small issues. Cheers.

For many years the Turkish army is the organisation Turks trust the most. We don't trust almost any organisation as much as we trust the army. The army is a honest, warm, nice place. Our military officers are getting an equal education to the universities and the quality is very high.
The Turkish army is not harsh at all. It is well known to make real men out of young boys. In some small towns old people will tell you that boys can marry only after they have finished military duty.
