Serbian / Croatian / Bosnian helmets with inscriptions

[joaobr]

The Serbian helmet has a shaved red star and some Bosnian inscriptions on the inside. They are: "January 1988", "May '89. This helmet was used in January 88" and also "gluttony". I don't know what the last one means.
On the front flap, it says: "II S V" with pen and "P7Z", crossed out on top.
I don't know what conflicts this type of helmet was used for. Would you have any good ideas?

 

The other helmet is a German model from DDR. It was a model used during the Croatian war by the Croats, together with other models of helmets.
There is an inscription on the liner that I can't quite understand ... I would appreciate any help!

 

I hope you enjoyed it and would like to know your impressions and what you think !!!

Thanks

Correcting an error:

The correct thing about the inscriptions on the helmet is:
"They are:" January 1988 "," May '89. This helmet was used in January 88 "and also" guja ".
