Beginning of Junkyard
 

At the broken bridge before the junkyard, I found two contraptions on either side of the bridge. They showed up red in my reticle, and I blew them up. They resembled the missile launchers you have to blow up in the Packrat Palooka boss fight.

I have yet to fight Palooka after blowing these contraptions up, so does anyone else know what they are or if they have an impact on the rest of the game?
