I'm no military expert, but for the plot line to exclude basic 2-way radio communications among a 6-man CIA-sponsored ISR team headed deep into the jungles of Venezuela, without any air support, seems contrived and juvenile. Of course it's needed to prompt Uber's irrational and otherwise unexplainable dereliction of duty (leaving the getaway boat he's been hired to drive) and thus set up Ep. 4 (which I'm not planning to watch due to my sudden lack of enchantment with this show) which will most likely center on the team's need to rescue Uber from the bad guys. I'm done with this series.
