SUGGESTED MODIFICATIONS Among the suggestions put forward by various commanders for modifying the 81-mm so as to make it more useful to the infantry regiment there were the following: Lighten it in "any manner possible" to increase its cross-country mobility. Build it so that it could be broken down from a long barrel to a short barrel, thus making a lighter pack possible while preserving its heavy punch at the short ranges. Sectionalize the base plate so that the load can be distributed. Alter metallurgically or in design the elevating screw, the breaking and rapid wearing of which is now the chief structural weakness in the weapon.

建议采取的改进措施：为改进81mm迫击炮，使其在步兵团中发挥更大的战术校能，多位指挥官提出了如下意见：尽一切办法减轻重量，以增强其越野机动性；改进结构，使长炮管可拆解更换为短炮管，这样就可以在保留强大的近程冲击力的同时减轻负重；分段铸造底盘，使负重均匀分布；改进升降螺丝杆的冶炼或设计，升降螺丝杆的损坏和迅速磨损现在是这种武器主要的结构缺陷。
