Sorry for long time but I've had a computer crash.....well, I think your unit is 31st Guastatori Engineer Battalion. Italian Army formed Guastatori units in 1940 on the example of german assault pioneers and their task was to assault and destroy fortified positions. IIRC the typical formation of a guastatori engineer battalion was on three assault companies of three or four platoon each. Each platoon included two assault teams and two covering teams. All personnel was volunteer. Only three battalions were formed, 30th, 31st and 32nd; all were destroyed in battle: 30th on Russian front and 31st and 32nd on North African.
32nd battalion was dissolved for high losses after Tobruk and remnants were adsorbed by 31st which fronted british at Alamein. 31st fought hardly either on Ruweisat Ridge and overall joined its doom at Folgore Para Division in last Alamein Battle in November. In particular, 31st is known for having been the only unit of X Corps which reached Afrika Korps thru british lines. 31st continued to fight until the last in Tunisia.
A large part of fame of 31st is dued to the personality of its commander, Maj. Paolo Caccia Dominioni, veteran of WWI and Ethiopia, explorer, painter and architect. After war, Caccia Dominioni will pass many years at Alamein recovering bodies of died in battle and collecting them in actual war cemeteries. He had also wrote his experience in some books which I don't know if they have been traslated in english
