Demonstrative

Explanation:

Those is a word for a demonstrative pronoun.

Demonstrative pronouns are those that are identifying and pointing out something. They can point out a person, a place, a moment, and can be singular or plural.

However, in this specific sentence, there is no pronoun, but those is used as a demonstrative adjective.

The words for demonstrative adjectives and pronouns are the same (this, these, that, those), but the difference is that the pronouns stand-alone, adjectives stand with the noun and modify it. The only difference is in the structure of the sentence.

Those stands with the word scouts and modifies it,  showing us which scouts do we talk about. That is how we know it is the case of the adjective and not the pronoun.
