RE: №0902, March 31st, 1945
Carrying out the orders of the Corps commander regarding the effectiveness of German anti-tank rifles and "Faustpatrone" grenades and losses in tanks and SPGs suffered from them, I report that during the fighting in East Prussia (January-February 1945) the brigade lost 1-2 tanks and one SPG near Trauvsitten to "Faustpatrone" grenades. No losses were taken from fire of "Panzerschreck" or "Ofenrohr" type weapons.
The brigade has no information on the organization of enemy units or their equipment with anti-tank rifles.
Chief of Staff of the 89th Tank Brigade, Lieutenant-Colonel Glushkov"
Considering that the brigade lost 50 tanks burned up and 38 tanks knocked out during February alone, Panzerfaust style weapons ended up doing a negligible amount of damage during the fighting in 1945 until the Red Army entered heavily built up areas.
