Are All Missions Small Scale
 

I am still on the Odessa campaign and the most number of units that I have controlled at one point is 2-3, in the second and third missions of the Odessa campaign I have one single squad. I am wondering if it's going to remain like this all the way through or if I will eventually get to utilize more units at one time.

In future missions you will have more units. The most I remember is atleast five squads and six tanks.
