I agree with Kelmola: I have only seen a few rounds on Sidi 32, but they all ended up in a massive bloodbath for the allies, who never even could get close to the first flag and were camped to death.
it's actually possible to get near the building for allies, provided you get some smoke nade deployed in the last moments (before you get pass those smaller buildings) to cover people who spawn later and run slower, but if you failed to get near the building in the first moments you are doomed, because,..
the scenario is like this, the Giant building is the most important location in the map, so who controling it would have an edge on enemies and exert bleed.
1. When axis controls the building: Axis troops would try to shoot anyone running to the building....
2. When brits controls the building: brits troops would try to shoot anyone running to the building.... however, there's a big difference, the axis side would attack from much more directions since they are very likely to have 2 flags to spawn from. that means camping is harder, there're a lot more cover out there.
