I found a studio named official sprinkle army what are armies

An “army” is sort of like a large alliance, made to withstand war.

then is there a topic or project about that that explains every thing about it?

it's usually a huge alliance, there's also “BTS armies” which is just a major fanbase of specifically BTS. usually these armies are either based off of fanbases or wars but since scratch doesn't really allow war-related stuff, so im assuming it's a major/small fanbase group

It's usually a studio made where people who share the same interest group up and then try to raid/mass-report other studios who “pose a threat” to them (AKA having a bigger capacity). If you see any studios doing this, please report it. It's also sometimes used as a fanclub.

a allience group, i did this a long time ago but it died

Basically a big group of people, but using “army” rather than “group” implies the group's somehow resilient to resistance. Here's two examples, with slightly different meanings:

• The US Army is a legitimate armed branch of the US military.
  
• Fans of BTS claim to be part of the (BTS) army. They're not armed with anything, they're just one big group that tend to “stand up for BTS” against any naysayers.

What you described is probably closer to the second example.

i think thats just warriors but ok
Some Scratch armies may just be really big fans, not aggressive people. Let's use this analogy:
US Army soldiers would die for their country::BTS Army members would die for BTS
