kidding me? how okw can turtle better than USF from start? OKW has less option than USF. USF have even better trutle options with super fast mobile reinforce and healing and free squads from teching and t0 mortar. they get t0 bunkers from the start and have superior infantry with super long range howitzer.
apart from motorized and 120mm, mortars are mostly crap, you get them only if you have to. Pak howie is OK, but nothing to write home about. leIG is worse then Pak Howie, but imo it is still OK and can be pretty useful.
By turtling I mean raks + behind hmg34 + 2 leIG type of turtling. Pretty cancerous, although does not work vs 120mm.
OKW gets stock heavy tank, that hits like a train. OKW gets really good elite non doc long range infantry, it gets premium medium with extremely good vet, 60 range TD with stealth.
As I said earlier, mentioning what options faction A has over faction B does not do justice to any of those factions. It is a moot point, because the factions are different, played differently, have different units with different pros and cons, with different teching and commander etc. If you just want to rant, just say so and I leave. No point in doing "my faction is worse, omg so unfair" type of discussions.
