I don't believe any of them did.. could be wrong. Maybe it's just something we just cobble together using fire extinguishers, duck tape, a can of pork and beans and whiskey.

hmm, still, I suspect we will only have a limited use of that PA, at least to begin with.

But helmets and pauldrons are interchangeable now. The battery-powered part would be the torso piece (I think), so we would have to look at which version that is.

Its the t45 torso, and only that one that says it in the demo.

A thought just occured to me. I was reading the leaked casting call from a few years back. In it Preston mentions they need a fusion core to power their weapons, and you mention you'll do it if you can keep the fusion core. Perhaps their weapons include that PA. Might explain why the T60 said core and not battery. Probably don't get to keep the armor but get the core. Ofcourse this is just speculation based on a few year old leak.
