> Most powerful mobile railgun was built by a non-government (i.e. this is the most powerful mobile railgun)
when in reality it probably is:
> Most powerful mobile railgun that was built by a non-government (i.e. there are more powerful mobile railguns)
Is the title ambiguous or is it just me?
I suspect that government defense contractors have repeatedly built man-portable prototypes that just don't measure up favorably against the .50-cal rifle. The government then mothballs the project again, until better electronics technology comes along. It also seems obvious that anything that did measure up would be classified as a state secret, so we wouldn't necessarily even know about it.
So the implication I got is that government-built devices are purposefully excluded, because we have no way of really knowing how powerful the most powerful government-built mobile railgun is.
