Hmm... This might be a problem...

For one thing, there won't be Skyrangers yet right at the beginning. For another, Skyrangers won't be armed as they need to free up as much weight and space as possible to deliver their most devastating payload yet: The troops.

But I like the idea of giving the Skyrangers weapons, but it will only come some time after XCOM receives its Skyrangers. And even then, Skyrangers can become eclipsed by more advanced transports, if you know what I mean :)
