Well since I have been INVOKED by Vor .. I shall chime in .. The M1 and the M9 Bazooka fired the same ammunition , this is true .. but the Ammunition changed a couple of thime thru the war .. In Game Terms The M1 is rated as using the M6A1 Bakooka rocket and the M9 as using the M6A3 Rocket. In Real life the M1 Bazooka was a solid tube , fixed primative sights and battery ignited, while the M9 was a two piece foldable tube, Optical sight , Magneto ignited weapon .. The PanzerShreck was solid tube fixed primitve sights Magneto ignited with a shield for backblast necsitated buy the rocket on the shreck continuing to burn after leaving the tube. Both Bazooka and Shreck rounds had a speed of about 100 meters per second give or take a small percentage for air temperture. Bazooka rounds had better ballistic coeffiency than Shreck round ( Panzer Faust rounds didn't have a Ballistic coeffiency near as I can tell , the warhead and aerodynamics were totally defined by the needs of the shape charge and not by any needs of air resitance conciderations) . While The Shreck having a much larger diameter ( which in shaped charges is more important than charge weight, but is connected to charge weight in a couple of ways) which results in a larger and deeper penetration. Larger is not necesarily better, the US Army is currently investigating a unknown weapon that recently knocked out an M1A1 Abrams Tank with a pencil sized hole that went clean thru one side and half way thru the opposite side after pentrating several key componets inside. This happen in Iraq last month. But deeper is always good . Both the M6A1 Bazooka round and the ShrecK round had a very pointed ogive that was more designed to provide a stand off for the shaped charge warhead with some small concideration for aerodynamics. Giving a mean dispersion in mils of about 6.5 IIRC while the M6A3 had a blunt more roundish Ogive that provided better aerodynamics and adequate standoff with a greater chance of detonating at the proper distance due to a larger frontal contact area and a mean dispersion in mils of about 4 IIRC. M6A3 has approximately 20% better penetration thru improvements in cone angle and an improved cone material. By way of a brief explanation, Monroe effect ( shaped charged weapons) have used a variety of cone liner material rangeing from glass thru copper , brass various copper alloys and iron and steel. By adjusting cone angles and materials you vary the penetration in different materials , what works well on earth or concrete will not work as well on armor plate for example and vice versa. Engineering Shaped charges for example, will use a shallow cone and a glass liner to get maximun penetration in earth with a cooler hole that allows TNT charges to be placed down the hole sooner for cratering operations. In real life this means a 8" diameter 15 lb Engineering shaped charge will pentrate 8 foot of packed earth ( ideal for cratering) but only 6" of Armor plate while a Modern 2" diameter 3 oz shaped charge will penetrate the 6" of armor plate but only about 6" of earth as well. In Real life all bazookas would have had the M6A3 ammunition by jan 44. In comparison the Shreck suffered from 3 negatives in accuracy .. the rocket burn time ( by this I mean a much longer unguided by the tube burn time ), the primitive sights, and the poor balistical effiency . The M1 bazooka with M6A1 suffers from 2 negatives in accuracy , primitave sights and poor balistical effiency , one negative is removed with M6A3 ammo .. The M9 bazooka suffers from no negatives unless using M6A1 ammo then the balistical effiency problem is added. Please note the "accuracy negatives" and the terms "poor" and "good" are relative within this group of weapons in this time period .. The PanzerFaust has all the negatives plus short range , but one heck of a warhead. On a side note I recently had the oportunity to examine a German K98 Grenade Launcher attachment, and noted the sights are calibrated to only 80 meters, this not to say that there are not other versions with different calibrations , there may very well be , but the collector I spoke with and that owned this seemed to think this was the most common version.
