The USMC has 24 infantry battalions I'm pretty sure that a few of them are capable of defeating The Black Watch.

Also something else you don't realize is that all 24 of the battalions are different from each other. When you consider each battalion has different SOPs, personnel makeup, and different leadership, there are some battalions that are better than others. For instance one battalion may be made up of brand new PVTs and PFCs while another may have a larger proportion of LCPLs who've all served one or two tours in Iraq or Afghanistan. The second battalion is obviously going to perform better, but within two years that battalion will be made up of mostly PVTs/PFCs, and the first will contain the larger proportion of LCPLs.

In the end it would come down to which battalion has more experienced and battle hardened personnel at the squad and platoon level.
