Base Attack Force - New Account

I am trying to open a new account (1st account as Newbee) with Base Attack Force. It puts me through tutorial in moving and capturing base, building resources and then I am asked to build “20 Stingray tanks to prepare for attack” but there are no Stingray tanks available in the menu and the blue arrow is pointing to M-41 Walker Bulldogs. The max in a group is 19, so can never get to 20. It just starts a new group. It will not allow m to make any other tanks or APC to capture a base. Help ?

Hello!

Are you sure you are on the right place? This is forum for Phoenix Point game (Phoenix Point on Steam) and what you are speaking about sounds like a different game.
