2 letters from 1943 sent from Italian "Regia Accademia di Artiglieria e Genio"( Royal Academy of Artillery and Engineers) from Lucca to Zagreb Croatia .
Croatian soldiers/officers were trained in Italy as well as Germany , an unknown number of officers was training with "Regia Accademia di Artiglieria e Genio" in Torino In November of 1942 due to intensive aerial bombardment , Accademia was moved from Torino to Lucca. This Croatian soldier Zvonko Barić writes to fellow soldier Ivo Košutić.

2nd. is from 5.1943 (two upper pics) mailed to Zastavnik(Fähnrich) Ivo Košutić a member of 3.bojna 2.Gorskog zdruga (3.battalion, 2nd Mountain brigade) in Zagreb, letter was redirected to Jablanica, last post office Konjic in Herzegovina. Academy cancel and Italian censor cancels are at the back of envelope,as well as Zagreb arrival cancel.
Mail from Italian military academies to Croatia is very very rare.
I have seen another cover mailed to Ivo Košutić by same sender, there his name is written Ivan Košutić. It is possible that this is Ivan Košutić(1921-1998) author of books about Croatian Domobranstvo in NDH, he served in Domobranstvo as well. Interesting thing about covers is that on the back of envelopes are written details from senders Croatian passport. He is from Đakovčka Satnica , a village near Đakovo , Ivan Košutić was from Punitovci a village near Đakovo maybe 2-3 km away from Đakovačka Satnica.. this could easily be letter mailed to him from a local friend...
