So 1:4 ratio... Would you assign them per Squad or as a Whole?
I can see 1:3 per Squad with four troopers- 3 Regular, 1 Handler and 3 Cyber-Dog per Squad, with 1 Cyber-Dog Squad per three Regular Squad as "normal", and a 2:2 for Assault.
We have K9 rules on using them, AToWC, but not to create them with Mapscale functions.
Troopers all have 1 point + armor divisor factor.
Troopers in BA is +1, after their respective rides loose BT Mech scale armor.
We can modify standard Troopers with extras.
How, where and can, a K9 be built, be it Battle Kat, Dog or other Exo-Fauna.
You can create them for RPG purposes, but not for Tabletop / Alpha Strike.
