I can’t speak about Hatzalah in Israel as I’m not sure.
But Shomrim/Shmira & Chaverim/Chavivim are duplicates. This is a problem which has plagued Yidden since time immemorial.
It’s either a member of an org who thinks he should be in charge that leaves & creates his own copycat service or a group that was rejected by the org so they create their own. Sadly, they often spend more time fighting each other or even calling the cops on each other instead of helping the community. There are videos out there of this happening.
The latest is in the Lakewood area they’re creating a new ambulance service like Hatzalah. There’s so much Lashon Hara going around there that you can’t know who to believe.
