Do I need to apply for a reentry visa while on my Non-Imm OA METV during my first year?

I've gotten some contrary info. I am in my first year of my Non-Imm OA METV. I'm from the USA. In my first year I do NOT have to apply for a reentry visa when traveling outside of TL... correct?? All my 90 day check ins are up to date. I had a few people tell me I need to apply for a reentry or multiple entry visa before leaving or it will void my visa. But I already have the METV status? Can someone clarify- I don't want to screw things up. I thought I would only need to start applying for reetry visas in my 2nd year.
