I was reading about modern and historical anti-tank weapons, both for fun and to have some knowledge to base my mod's "bazookas" in. I got curious about a few things, and I remembered that there are many people who knows a lot about weapons here.
Most good materials are in English and I'm not a native English speaker. Also, I do not have much knowledge about weapons anyway. So, please, keep that in mind if any of my questions turn out to be actually silly thoughts.
First, in the following video, at 0:25, the soldier pulls of a retractable part of the M72 LAW:
Spoiler:Does that thing be retractable only to make the weapon smaller when not in use? Or to protect the user's shoulder against the rocket's flames? Or are there other functions of that?
Also, I could not find videos of soldiers reloading this weapon. How is it done? Does the rocket go from behind the weapon? Or is it in front, just as a Panzerfaust?
Also, about the panzerfausts, I've read more then once that they are "disposables". The translation of this to my language would be "descartável", meaning some thing that is discarded after used once. Are panzerfausts used only once? If so, is it the whole weapon the goes into garbage? Or maybe only part of it? I've seem a panzerfausts being (re?)loaded in a video, soI got confused about this "disposable" predicate. Can it be reloaded and shoot again after being used?
As always, thanks in advance.
