Any high resolution scans help. I have started to look at the scans.
From picture 1, 3 and 4. My comments are in the brackets.
He participated from June 6 1940 to I Oct 1942 and from Nov 11 1942 to Mar 17 1943 in war[time] operations in A.S. [Africa Settentrionale/North Africa] in the 330° raggruppamento art da G.A.F. [Guardia a Frontiera which is a border guard organization with wartime functions].
[My guess is that the gap was 1942 is home leave. The 330° raggruppamento art da G.A.F. was equipped with either 77/28 or 100/17 guns, depending on to which gruppo he was assigned].
There is something about service at Bardia (or not, I am unsure of the spelling), but I can't make it out.
He has some type of service from 9 Sep 1943 to Feb 20 1944 [again can't quite make it out].
He is credited for four years of wartime service: 1940, 41, 42, 43, and 44. This is important as he is authorized to wear four stars on the medaglia Distintivo della Guerra in corso [distinctive medal for the current war; basically a WW2 service medal]
He received a Croce al Merito di Guerra [War Merit Cross] under the provisions of 14 Dec 1942 regulations for his service in wartime from 1940-1943. This is not a valor award, but is awarded for superior service. This could have been awarded postwar.
It appears he was officially discharged from all military service on Jan 9 1960.
