English Other Government / Politics Irish Police

Hello,
I have the above term, which I believe to be Gaelic! The term appears in the following sentence:
"In a welcoming and relaxing atmosphere, you will have the opportunity to meet local Gardai and receive information about An Garda Siochana, *Garda Reserve* and specialised units within An Garda Siochana.

Is there an English translation for this term?

Thanks in advance,
Mark
