This isn't the greatest (for acuracy and clarity) but my BC-654 is now a lot more special to me...

Hello Phil,
The file on the artillery mission is FUBAR. The US voice call for fire has changed very little since World War Two, and follows a very specific format. It basically goes like this:

FO - "(Fire Direction Center {FDC} call sign) this is (Forward Observer {FO} call sign), adjust fire, over"

The forward observer could call for another type of mission, such as "illumination" or "Fire for Effect" along with either a target number or a grid location if the observer is absolutely sure of the target location, but the adjust fire is the most common type of mission.

FDC - (FO call Sign) this is (FDC call sign) adjust fire, out."
FO - " grid able charlie 657343, over."
FDC - "grid able charlie 657343, out."

The Forward observer could use a different method of adjustment for this fire mission, such as "Polar Plot" or "Shift From A Known Point", but "Grid" is the most common method used.

FO - " six tanks refueling. HE VT and WP in effect. over"
FDC - "six tanks refueling. HE VT and WP in effect, out."

The FO has called for specific shell/fuse combinations to be fired in the "Fire For Effect (FFE)" portion of the mission. The FFE portion of the mission is when the entire element supporting the FO fires. Normally in adjustment, one gun fires while the rest follow the mission, making adjustments so they are ready to fire when FFE is ordered. For this mission, the FO has called for High Explosive shells fitted with airburst Variable Time fuses, and White Phosphorous shells with Point Detonating (PD) fuses to be fired on the target (6 tanks refueling). The HE VT shreds the fuel drums, the WP rounds set the fuel on fire. The standard shell/fuse combo in the fire for effect is HE PD. If the FO doesn't request a specific shell fuse combination, he will normally get HE PD in whatever the standard amount of rounds the firing unit uses in the FFE.

FO - "Direction 146, request splash, over."
FDC - "Direction 146, request splash, out."

The FO sent the direction from his position to the target, in Mils (not degrees) to the FDC so the FDC will be able to "see" the target from the point of view of the FO. The FO requested splash, which means the FDC will radio the FO 5 seconds before the round(s) land, so the FO can stay under cover until the last possible moment and still observe how the round(s) land and make adjustment.

FDC - " Mike Tango Oscar, (firing unit callsign ) two rounds, over."
FO - " Mike tango Oscar, (firing unit callsign) two rounds, out."

The FDC just sent the FDO an "Message to Observer" (MTO) that told the FO who and what size unit was shooting the rounds he requested, and that unit is going to fire two rounds of the shell fuze combinations that he requested. The FDC, at their discretion, could change the shell fuse combination the FO requested in the FFE portion of the mission. If the FDC changes the shell fuse combination to be fired in effect, it must tell the FO in the MTO. For instance, the FDC could have sent " MTO, (firing unit call sign) one round HE PD in effect" which tell the for he isn't getting the VT fuzes or the WP rounds he asked for.

FDC - "Shot, Over."
FO - "Shot, Out."

The FDC just let the FO know the firing unit has just fired the adjustment round. The FO acknowledged.

FDC - "splash, over."
FO - "splash, out."

The FDC just warned the FO that the round that was just shot will impact 5 seconds from the end of the warning they just sent. The FO acknowledged.

FO - "right one hundred, drop one hundred, over."
FDC "right one hundred, drop one hundred, out."

Adjustments are done in meters. The FO tells the FDC how to move the impact of the adjusting round on to the target, from his point of view. The FO will normally try to bracket the target, unless they are REALLY good and can adjust the impact of the first adjustment round right on to the target. Adjustments are sent, either "right " or "left", "add (move the impact of the round further away from the FO) or "drop" ( bring the impact of the round closer to the FO) in increments of 50 meters

"shot" and "splash" transmissions are sent again. The observer will bracket the target with adjusting rounds until the impact of the adjustment fire is within 50 meters of the target. When that happens, the FO sends the final adjustment

FO - "Left 50, add 50, fire for effect, over."
FDC - "Left 50, add 50, fire for effect, out."

FDC - "Shot, rounds complete, over."
FO - "Shot, rounds complete, out."

The FDC just let the FO know that the unit firing has shot, and that all the rounds he requested in effect are on their way to the target. The FO acknowledged.

FDC - "Splash, over."
FO - "Splash, out."

Five seconds later, the FO will observe the FFE impact the target.

FO - "Target, End Of Mission. Six tanks burning. Estimate 35 casualties, over."
FDC - "Target, End Of Mission, Six tanks burning, Estimate 35 casualties,out."

The FO just told the FDC that some rounds from the FFE actually impacted on the target. This is not common. The FO tries to have rounds land close enough to the target to put the desired effects on the target (normally within 50 meters). In that case, the FO would send minor adjustments (smaller than 50 meters) back to the FDC, along with "End of Mission" (EOM). The FO does not send EOM unless the FFE has had the desired effects on the target. The FO may send further adjustments of 50 meters or more (especially if the target decides to move) to get the desired effects on target, or he may send "Repeat" which tells the firing unit to fire again using the same targeting data as their last shot(s). (This is also why radiomen NEVER use the word "Repeat" while talking on the radio. The correct way to ask somebody to repeat what they just said is to say "Say Again." The FO will also send a brief description of what the FFE did to the target back to the FDC.

Updated the links per a request I received.

Pease note - I did NOT create these files. I do not check for accuracy since I did not make them. They sound good when played out of a Bluetooth speaker I hide near my radio.

Updated links since I received some messages that Google isn't playing nice with some people. Hopefully these work.

I also added a new file - this is the audio from the end of each episode of Generation Kill stitched together. I play this in my HMMWV at shows.

Thanks a lot for refreshing the links. I have installed your MP3 files in a few modified WWII radios.

For those interested in other periods chatter files (AWACS) and Vietnam war helicopter pilot chatter files, here are the links:

AWACS radio chatters
https://www.lazygranch.com/red_audio.htm

Above in the page, you have the audio tools.
Below you have the AWACS radio chatters Red Flag captured with a radio scanner

There are much more chatters from the Vietnam War. (listen to the last one in that series for example:
http://www.135ahc.net/radio-chatter/
To bad that there is the helicopter sound :)! That's not correct for WWII radios :lol: !

Here below, I have converted the amazing battle of Guam tank battle radio chatter into an MP3 file

Thanks for the links Yves.
I have not listened to all of them, yet.
I went to the Vietnam link first. That hit the flash back button.
Didn't mind the chopper flutter but I could have done without AFVN music playing in the background. I have tapes I recorded personally for that.
Still good stuff.
