so here:
take PF doctrine
-kubel
-SP
-kubel
now the triky part
you go fast mechanized to get to 2 cp
go spam the PF(you want around 4 squad)
now your choice
do the enemy go for LV ? -> puma
do they go heavy on inf ? -> luch
do you have to fair with a 2 min blobber or sim city? -> stuka
then med with FRP
get another puma
you want your army like this
4xPF 2xSP 2xpuma 1xluch and 1xstuka or 2 stuka
wait for jt if you want you can go tier 3 but be aware you want the JT eraly before they mass tank
dont forget to up you PF with g43
now the enemy can t rant on the forum how op free tier 3 or vloks are because there were none


Edit: can we put after the title (breakthrough doctrine) please
