As @LucianSava commented this is the imperative mood.
The 'imperative mood' is a grammatical mood that forms commands or requests, including the giving of prohibition or permission, or any other kind of advice or exhortation.
In this grammatical mood we can position two verb with a null conjunction (and), however, we can include the conjunction and the meaning will not change. Most sources say that the null conjunction is mostly relevant in the US while the conjunction and is relevant in the UK. Saying something like “Go make me a drink” is distinctive as part of American English in particular.
- Go (and) take this book to Mom.
- I'll go (and) bring myself a glass of water.
- Come (and) sit beside me.
Come and Go can both take a bare infinitive that's why such constructions are possible.
There's an interesting moment about stacking verbs in the imperative mood, see here: Should I always insert “and” between two verbs in the imperative mood?
