Likely this was a 61mm mortar round and the little fellow will not damage barbed wire much, each roll weighed in excess of 100 tightly packed pounds. We did not have gloves available so working with it cut us. Working with it was punishment worse than burning shit. The rolls of barbered wire were often used to slow or prevent the enemy getting inside our base by stringing it around stakes driven into the ground thus creating a web of tightly strung barbed wire, 2 or 3 inches off the ground. The rolls were also placed in front of a shaped charge so as to shatter the roll into small fast flying pieces that were very effective in clearing an area of live people.
