Fire Force - Season 2
The following weapons were used in Season 2 of the anime series Fire Force:
The Daewoo K5 is seen with Takehisa Hinawa in "Mind Blown".
Heckler & Koch USP
The Heckler & Koch USP is seen with Takehisa, showing in the OP sequence, "SPARK-AGAIN".
The Minebea PM-9 is used by Takehisa as his main submachine gun in the season.
An Ithaca 37 appears to be used by Takehisa to fire buckshot rounds powered by his Fire Soldier powers in "A Fire Soldier's Fight".
Saab Bofors Dynamics AT4
A Saab Bofors Dynamics AT4 appears to be use in "A Fire Soldier's Fight". The sound effects used in the episode makes it sound like the AT4 is configured as a multi-shot grenade launcher.
The Extinguisher grenades return from the first season, being used as a non-lethal weapon to subdue flames or a distraction device against Infernals since tossing one makes smoke.
