BGB wrote:The rules for taking saving throws and removing casualties... assume that all the models in the target unit are identical in gaming terms. By this we mean they have the same profile of characteristics, the same special rules and the same wargear.
Let's break it down:
1. Profile - they quite literally have the same profile of characteristics, even though it is listed separately.
2. Special Rules - there are no special rules to separate the sarge from the others; he operates in the exact same way as his brother terminators.
3. Wargear - this is the only item that is mutable within the squad, and depends on how you've upgraded your marines.
I see the argument, and I think I understand why you're making it (as in, what purpose it would serve). However, I think by specifically stating the "same profile of characteristics" in combination with "identical in gaming terms", they solidify that this is a case when the sergeant is no longer differentiated from his squad.
