How does it need to be unmarked? They're training to detain targets in an urban environment. They are training on US soil, and they are using US citizens in the training, because you don't train for detaining targets in a foreign city by detaining actual hostiles in a foreign city. You train under circumstances that are entirely within your control, with fake targets who are in on it and effectively playing a role.
That exact same training, however, is applicable to detaining a hostile in Baghdad, catching a North Korean agent on a base in Okinawa, securing a diplomat in a threatened consulate in North Africa, or taking down a high value target in a secret operation in a Pakistani border town.
To be fair, yes, it would also be applicable to detaining US citizens in a US city. However, the above is just a few of a very, very long list of ways the US military has actually detained a person in a city, for which this is accurate and useful training.
