Captain America's Retro Walkie-Talkie

Steve Rogers is all about old-school heroism, so what better tool for him than a retro-style walkie-talkie? Imagine Captain America leading the charge against a Chitauri invasion, barking orders into his trusty device: “Fall back! Form a perimeter!”
The retro design would fit perfectly with his WWII aesthetic, and the walkie-talkie could even have a built-in Morse code feature for those times when subtlety is key. Plus, it would give Cap one more reason to say, “I can do this all day.”
