Theres loads out there but I am not member myself.
I know someone who joined after he went to rehab...some people need the disicpline of an army to get them to walk uprightly after going astray. It first started out as a mission for the poor in England. They had really bad poverty over there and the exisiting church wasnt doing much about it.
So General and Catherine Booth founded it to reach out to the poor. Thats why theres so much activity/charity things like rehab centres, budget advisors, clothing op shops, foodbanks, services to find lost children, foster homes, christmas appeals...the church of england at the time wasn't really doing anything to reach the poor and they weren showing much charity, mostly only rich people went and snubbed the poor. But the poor need salvation and to know Jesus too.
They dont have lords supper or baptism, because they were ministry first and not offical church but I think now you can go worship at the salvation army and maybe have that elsewhere. Its very organised so be sure you really want to commit to it people spend their whole lives in it and move up the ranks. They have things like uniforms and designated posts.
