What kind of communication was there in the Vietnam war?

Answer 1

Battlefield communications is rarely touted and often maligned in military history. The VHF communication band for the military int those days was divided as follows: Armour/Infantry/Artillery and it was designed that way for a reason. The Infantry radio frequency had to overlap both sides to call in support. HF or High Frequency communications was designed for long distance communications (over the horizon) and for communications from ground to air a separate link had to be established. Enter Ultra High Frequency (UHF) for air to air and air to ground communications. A completely different radio was required for this purpose. In modern warfare such rules no longer exist. Sattelite communications and the development of transistors and solid state technology has altered the whole communication paradigmn. For HF communications back to a ship or base camp you needed an AN/GRC-9 that needed a crew of three and to talk to an aircraft a 40 pound MAY-1 and its two man crew was essential.

Line of sight was easy, just hump a 30 pound VHF radio in additon to your regular combat gear.

It didn't matter. If the battle failed, blame it on a lack of communications.

.... do with the Vietnam War by making it easier for the men on the ground to talk to the men in the skys to organize bomb strikes.

Answer 2

Radio AN/PRC-25 As per the answer above, backpack radios were used widely by the infantry, given their portability, and decent reliability. Helicopter and vehicle crews had the advantage of larger, fixed radios as did artillery men.

Should radios fail, the average infantryman carried at least one, and occasionally 2 color-coded signal smoke grenades (Purple for medevac, green for pickup, etc.)
