Russian uses the Cyrillic alphabet, which looks a bit scary at first! But actually the hardest part is NOT the scary letters (Д, Ж, Ф, Ц, Ч, Ш, Щ, Ы, Ю, Я) because you can just learn these, but the letters that look like English/Latin letters but that have different sounds (you have to "un-learn" these first, then re-learn a new sound!)

А а	"Ah" like in cat
Б б	"Buh" like in butter
В в	"Vuh" as in viking
Г г	"Guh" has in gate
Д д	"Duh" as in dog
Е е	"Yeah" as in yet
Ё ё	"Yo" as in yolk
Ж ж	"Zhuh" as in pleasure, azure, also like Je in French
З з	"Zuh" as in zebra
И и	"Eee" as in egret
Й й	"Ih" as in igloo
К к	"Kuh" as in kill
Л л	"Ell" as in letter
М м	"Muh" as in mother (n.b. not "Em")
Н н	"Nuh" as in nice (n.b. not "En")
О о	"Oh" as in Oliver
П п	Puh as in pie (like the Greek letter)
Р р	"Rrrrr" as in rrrrrrrrroll your Rrrrrrr's
С с	"Ssuh" as in snake
Т т	"Tuh" as in take
У у	"Oooo" as in Luton, Boot,
Ф ф	"Eff" as in fridge
Х х	"kH", sometimes the K and the H are both sounded like in Mikhail, sometimes just the H as in hotel.
Ц ц	"Ts" like in its
Ч ч	"Chuh" as in chips
Ш ш	"Shah" as in shut
Щ щ	"Schah" as in sheep
Ъ ъ	Soft sound, used to make previous sound softer, turns the L in Olga (Ol-Gah) into more of an Oil-Gah.
Ы ы	"Oi", the hardest sound to make. You have to stretch your lips out sideways. I can't find an English work that has this sound!
Ь ь	Hardening sound.
Э э	"Eh" as in echo
Ю ю	"Yoo" and un union
Я я	"Yah" as in yak

Usually О is said as А if another letter is stressed. Apparently only "villagers" always say О as О.
For example, the word for female friend is said Padrooga, and not Podrooga, because the у has the stress:
Подруга
PadrOOga
