How were the radios divided up? How many?Richard Anderson wrote: The US equivalent was the JASCO - Joint Assault Signal Company. ... the JASCO was commanded by a major and comprised 502 O & EM, both soldiers and sailors. The company was divided into a HQ (3 O and 74 EM), a Naval Shore Fire Control Section (18 O and 45 EM), an Air Liaison Section (13 O and 39 EM), and a Beach Party Communications Section (10 O and 190 EM).
Each JASCO typically formed nine or more Naval Shore Fire Control parties. ....
To digress briefly.
One of the bitter lessons the Marines learned was that during an assault all radios were fire control property and all radio networks fire control. When the NGF spotting team went down or its radio failed every other radio in reach was the back up. Did not matter who thought they controlled the radio, during those critical minutes or hours the fire support owned it. Thus when the radio operators and supervisors back at the CP of the Messkit Repair Company had a call for naval gunfire support come in on their radio frequency they had to be trained to recognize it and rapidly forward the message to the NGF control. No excuses, no hesitation. The lesson became institutionalized and reflected in our training in the 1980s. During my years as a artillery FO in there were a couple occasions I sprinted from my RO to the next nearest and relayed the call for fire via some other network. Messy, but critically essential.
