Dunno about BTS but in this mod they're a 50 hammer str40 1-shot collateral unit. So I'm thinking they're a catapult that's 8 times stronger than normal 
. They can only travel 4 tiles so they're primarily defensive (boo!) unless you have very tight borders or a fleet of submarines. We're a long way from Radio, but who knows if someone will sell us a sub or two when they get there? Of course Jetboy is only four tiles from MusketShrine 
.
On the GG - if we settle him in Jamestown we're producing 16XP - one short of Commando out of the gate
. If we'd kept our previous guy rather than sprinkling XP we'd have 18XP, but I'm more inclined to sprinkle again for another seven Commando units... Or we switch from Bureau to Vassalage for a while since our capital isn't particularly amazing any more!
