The only challenge i experienced in campaign was the second german mission. Maybe the first german was ok too, as it was unclear where enemy would strike. But all the american, scottish and two latter german missions are somewhere between easy and faceroll tiers.
Not to say, that all of them are really short, missions are usually won in 20 min or so, and there are only 4 of them, so a whole campaign could be done in hour and a half. It's also mostly prevents player from using phase C units - they arrive too late, and in very little quantity.
I hope for more campaigns in DLCs, and i wish those campaigns be much more difficult, longer (time in single missions and overall quantity of missions), and, maybe, a bit more tactical - i would gladly buy something like first able archer mission in EE, where you get a small kampfgruppe and no reinforcements(except for secondary objectives), but a whole map with a lot of different tasks and objectives.
