Looking for that good (free) Panzerchreck info?
The Tank Museum has three training manuals for the Raketenpanzerbüchse also known as Panzerschreck or Ofenrohr, as well as other tank-killers, up for free downloads.
You are welcome.
Speaking of bazookas, the Army just approved 1,111 M3E1 84mm recoilless rifles for immediate use as a lightweight (titanium) reusable replacement to the standard M3 Multi-Role Anti-Armor Anti-Personnel Weapon System (MMAAWS)– better known as the Carl Gustaf.
