'''Panzerschreck''' (sv. "Pansarskräck") även benämnd '''Raketenpanzerbüchse 54'''. Tyskt rekylfritt bärbart pansarvärnsvapen från andra världskriget. Panzerschreck utvecklades efter att man undersökt erövrade modeller av den amerikanska bazooka (vissa källor uppger att inspirationen kom från erövrade Lend-lease "ryska" bazookas på östfronten). Panzerschreck tillfördes fältförband under senare delen av 1943, efterhand i större mängder. Panzerschreck blev dock aldrig det mängdvapen som den lättare Panzerfaust var. I januari 1944 hade drygt 21&nbsp;000 Panzerschreck tillförts fältförband. Den sammanlagda produktionen var omkring 215&nbsp;000. 

Vapnet betjänades av två man - laddare och skytt. På grund av vapnets storlek och utseende gav soldaterna det öknamnet ''Ofenrohr'' (kaminröret).

Panzerschreck verkade enligt RSV-principen och hade omkring 150 meters räckvidd (statiska, stora mål kunde bekämpas på längre avstånd). Genomslagsförmågan i granaten var tillräcklig för att slå ut praktiskt taget alla sovjetiska och västallierade infanteriets pansarvärnsförmåga och var ett lämpligt vapen för de defensiva striderna 1943-45. I jämförelse med pansarvärnskanoner var Panzerschreck mycket kostnadseffektiv.

Panzerschreck tilldelades skytte- och pansargrenadjärkompanier från och med slutet av 1943. Pansarförstöringsgrupper, ''Panzerzerstörertrupp'', organiserades på kompaninivå med två-fyra stycken Panzerschreck. Även skytteplutoner och enskilda skyttegrupper kunde vara beväpnade med Panzerschreck. Även fristående kompanier, ''Selbständige Panzer-Zerstörerkompanie'', utrustade med 72 stycken Panzerschreck sattes upp.

Hettan som utvecklades vid avfyring innebar att skytten ibland bar skyddsmask för att skydda ansiktet. Fotografier finns som visar detta.
 
Vapnet exporterades till Finland under 1944 och användes av finska armén mot Röda Armén under sommaren 1944.

'''Panzerschreck''' (German: ''tank shocker'') was the popular name for the ''Raketenpanzerbüchse'' ('rocket tank rifle', abbreviated to RPzB), an 88 mm anti-tank rocket launcher developed by the Germans in World War II. Another popular nickname was ''Ofenrohr'' ("stove pipe").<ref>{{Citation

It was given to infantry to bolster their anti-tank capability. The weapon was shoulder-launched and fired a rocket-propelled, fin-stabilized grenade with a shaped charge warhead. It was made in much smaller numbers than the highly successful Panzerfaust, which was a disposable recoilless rifle firing an anti-tank warhead.

In 1941 the Germans encountered the new Soviet tank designs such as the P.z.b 39 anti-tank rifle called the M1A1 "Bazooka". Later in the fighting in Africa, German troops captured many Allied North Africa as well as some lend-lease versions on the Eastern front. The German army quickly assimilated an improved German version of the M1A1 Bazooka, the Raketen-Panzerbüchse, which had double the penetrative performance and used a bigger 88 mm round. Although this was a much heavier round than its Allied counter part, it proved itself against Allied armor on all fronts, earning the nickname "tank terror".

The first model was the RPzB- 43 which was 164 cm long and weighed about 9.25 kg when empty. Operators of the RPzB 43 had to wear a protective poncho and a gas mask without a filter to protect them from the heat of the backblast when the weapon was fired. In October 1943, it was succeeded by the RPzB 54 which was fitted with a blast shield to protect the operator. This was heavier and weighed 11 kg empty. This was followed by the RPzB-54/1 with an improved rocket, shorter barrel and a range increased to about 180 meters. 

Firing the RPzB generated a lot of smoke both in front and behind the weapon. Because of the weapon's tube and the smoke, the German troops nicknamed it the ''Ofenrohr'' ("Stove Pipe"). This also meant that Panzerschreck teams were revealed once they fired, making them targets and, therefore, required them to shift positions. This type of system also made it problematic to fire the weapon from inside closed spaces (such as bunkers or houses), filling the room with toxic smoke and revealing the firing location immediately. This was in contrast to the British PIAT's cumbersome, but non-smoking system, or the Panzerfausts short burst launch system.

The Panzerschreck was an effective weapon. Allied bazookas had problems with new up-armored German armor present on German tanks, most notably the Tiger tank and the Panther tank. By comparison the Panzerschreck rocket could penetrate over 200 mm of armor, which was not found on any Allied designs, but paid for this extra hitting power with extra weight. The rocket projectile weighed 7.25lb, 3.3Kg. Hogg notes the penetration at "about 100mm".

One direct hit was usually enough to destroy any Allied armored vehicle. When handled by well-trained crews, this weapon became the bane of Allied armored units, who frequently attempted to add improvised protection to their tanks, e.g. sandbags, spare track units, logs and so on. Most of this make-shift protection had little actual effect. <ref>Belton Y. Cooper ''Death Traps'' pg. 229, 1998</ref>
