Hey y’all. i just want ya to know that the GP-5 mask with a modern nato standard 40mm thread filter works extremely well in tear gas and other irritant chemicals like that green gas that’s used sometimes. source for this is me wearing this mask as i ran a confidence course for the army back when i was a chemical ops specialist. i tested a few of my personal masks as a side quest. i can try to answer some questions if anyone has them.
