I’ve never troop built before.

Troop Build: Amassing multiples of the same figure, more often than not based on a generic “canon fodder” character – in this instance, the Deception Vehicons (both the car and jet variants) from Transformers Prime.

The figures specifically are:
Transformers Prime Deluxe Vehicon (Hasbro, US) x2
Transformers Prime AM-14 Arms Micron Vehicon (Takara, Jap) x1
Transformers Prime AM-16 Arms Micron Vehicon (Takara, Jap) x2
