What is that 4th +15 fuel from?
Nobody going for the P4 will tech both buildings and not get any vehicles, it's more like:
15 + 25 + 15 +120 + 150 = 325 Fuel for P4
Later of they go for mechanized, but if you go for mechanized you probably aren't going for a P4.
Whoops, lost count of supply halftracks.
If they stay mech for puma's and shit, they will lose to t-34's anyway. Most players get the fast luchs that I've seen.
If they go BHQ to Panzer it's still 175 fuel in tech and 150 for pzIV.
