On orders of the Chief of Artillery of the 22nd Army I send you information regarding penetration of 76 mm and 107 mm HE and 122 mm and 203 mm concrete piercing shells.
The data was obtained at the ANIOP firing at plates angled at 30 degrees from normal.
When firing at plates at normal the penetration is 15-20% higher.
Have all commanders of artillery regiments familiarize themselves with this data.
