The Sangheili swordsman will they be in Halo War 2

They are seen in the E3 Trailer so i think they had to be in the gameplay but i don’t see them ,i love those guy such a cool units, but Halo Wars 2 is still in beta so i think they just not available yet or am i wrong ?In the Trailer you can clearly see them here file:///C:/Users/PC/Desktop/My%20Files/Halo-Wars-2-trailer-battle.jpg
