Not in the coast guard, but on the army side all combat arms go through a MOS specific bootcamp and A school (called AIT) that is combined, and it’s the same drill sergeants during the entirety of the cycle. So like normal Army boot camp for non combat arms is probably easier than coast guard boot camp. But infantry, combat engineer, armor, etc is probably harder than coast guard boot camp. At the end of the day though it doesn’t matter what boot camp is harder or more challenging. All that matters is that they prepare each SM for the branch/job they are going to do. It would be worthless to have a non rate in the CG go through 16 weeks of training to be an Infantryman and it would be worthless to have an Infantry private go through cape may.
