Captain America, Spider Man, and Thor are proudly displayed on this 100% cotton Marvel Kids Superhero Squad Big 3 T-Shirt. Captain America has the ground covered, Spider Man is close air support, and Thor is the big guns. I think in military doctrine that is what they call 'combined arms'. Where is Tony Stark when you need him? Probably off drinking somewhere. Regardless, this Marvel Kids Superhero Squad Big 3 T-Shirt comes from the hit TV show and is made for the munchkins. How can you go wrong with a cartoon based on super heroes? If you can't figure it out, ask your kid! I'm sure they'll spend copious amounts of time explaining it to you.
