It depends. Grenade could potentially be part of a historical fiction story if it's placed in a historical context and used to tell a fictional tale based on real events or periods. But without more context, it's hard to say for sure.
I'm not sure specifically which 'museum secrets grenade story' you're referring to. It could be about a historical grenade on display, perhaps a unique design or a story behind its discovery in the museum.
Grenade launchers in science fiction are frequently modified to fit the unique settings of the genre. They can be integrated with other technologies, like being part of a multi - weapon system on a spaceship or a mecha. In some stories, the grenades themselves can be programmable, allowing the user to set the detonation time or type of explosion precisely. This gives the weapon more versatility compared to traditional grenade launchers. Also, the appearance of these grenade launchers may be more stylized, with glowing parts or unique markings to make them stand out as a piece of advanced weaponry.
One common use is for anti - vehicle combat. In many science fiction scenarios, there are large, armored vehicles or mechs that regular firearms can't easily take down. Grenade launchers with their high - explosive power are perfect for disabling or destroying such targets.
There's no way to really tell if it's common specifically for someone named Jojo. However, in general, reading fanfiction is a popular activity among fans of many different franchises.

Perhaps this Jojo is interested in exploring different interpretations and stories within the Jojo universe that fans have come up with. Fanfiction often takes the existing characters, settings, etc. from the original Jojo series and creates new and unique storylines. So, this Jojo might be a big fan of the series and wants to see what other fans have imagined.
In the museum secrets grenade story, it might be that the grenade has some hidden markings or inscriptions that tell a story. These could be military codes, or perhaps the name of the unit that used it.
It depends. Maybe there are some telltale signs or elements that suggest it's a JoJo reference fanfic, but without specific context, it's hard to say for sure.
