smoke bomb function

when I throw a smoke bomb and the character is inside the smoke, does that make the character invincible or invisible to enemy attacks, because there are some really annoying bases that gather in one place with all their resources and even their watchtowers

The smoke area of effect disables targeting though, in, and out of the smoke to other ground units. It is useful for when you need to cross dangerous territory while minimizing exposure to enemy positions However, enemies placed in towers can still see over the smoke so you can't use it to break line of sight that way
