Is a bass clarinet in the marching band?

Our band is pretty small but we have 2 bass clarinets so yeah, bass clarinets are in marching band.

Yes, they are in marching band. I have a marching band of 209 and we have 3 bass clarinet marchers. I will be marching next year. I currently play clarinet. But don't worry, when I was in 8th grade I didn't know that they were in marchin band.
