The forces beating down Valens and his roman army there had been called the 3 tribe confederation (translated into English, so it might spell different). However it was had been forged by 3 groups:

1st The Visigoth forces under Fritigern as a main force with almost common Germanic armed men. In opposite to the Ostrogoths the Visigoth had not as much effort into mounted warriors.

2nd A mixed up random group and people that became Horde earlier by the trouble the Huns made in the east. Here you found a reasonable mounted force of Ostrogoth steppe riders, on the move since the Huns destroyed the very big Ostrogoth Empire of Ermanric and did not resigned to their new heirs.
Next part was a very big pack of Alan steppe riders on their way west, since the Huns had conquered their homes before the year 375. In a consequence you can find them in RTW BI as a regular mounted archers unit to build for the Goths too.
With them there was a small pack of Huns still on the move that had not been happy with the situation and powers with the original Horde of the Huns.

This coalition beat up the Romans at Adrianople and had been lead by Fritigern. Up to this time most Visigoths settled more as farmers but as cattle-breeders in their homes and used more conventional kind of warfare. With this success and the fact they had been forced to stay in nearly constant move of their Nation until they settled down in southern France and Spain later on, they occupied a lot of the steppe warfare.
