Don't let their green outer shells fool you. Troop-carried radios have evolved quite a bit over the last 70 years. They have gone from AM to FM, from vacuum tubes to transistors. They have conquered frequency drift, made better use of the spectrum, and added integrated encryption and frequency-hopping capabilities. The newest radios are software-defined for easier upgrades, and they can transmit images, video and GPS location as well as voice. Finally, mobile ad hoc networking holds out the promise of better communications in a highly dynamic environment. And as all this happens, the equipment keeps getting smaller.
