Talk:M40 recoilless rifle

message: Actually, even if they are not experts, these editors of this page have gotten their facts right on.  Not many people know about the Swedish 106mm round that gives astonishing performance and the fact that while it is designated 106-mm its caliber is 105-mm.

message: I went through the article again with a critical eye and the following points occurred to me. I am going to post them ane wait several months for comment before I change the article - so I would appreciate feedback from readers.
1. Have a link to the Recoilless Rifle page - http://en.wikipedia.org/wiki/Recoilless_rifle
2. The question of why the weaapon was designated as "106" mm is a vexing one. My understanding has always been that the ammunition was incompatible with the 105mm M27 and to avoid confusion in ammunition supply and possible safety problems, the "change" in caliber was decided upon. Frankly, I don't trust secondary sources here - they may all be echoing each other as the parrot the story "everybody knows". Short of visiting the National Archives and crawling through the Ordnance Committee minutes of the period - and even then, they may not include the reasoning but just that the Committee approved the new designation - I don't think a citation is possible. I think "weasel words" like "It is commonly thought that the reason for the change was etc."
3. Include the fact that the tripod mount was the M79
4. Combat use - Seeing that both the Israelis and Jordanians had them, they were probably used in the 1967 and 1973 Mideast Wars. Additional candidates are the Iran-Iraq war(Iran)and Lebannese Civil Wars. I quesstion its use in the Falkland Conflict as the Argentines are not listed as users and the British did not use the M40 series - their equivalent was the 120 mm BAT/WOMBAT/CONBAT (http://en.wikipedia.org/wiki/L6_Wombat). 
5. Repleacement by the BGM-71 TOW system is, to split hairs, incorrect. BGM-71 is the designation of the missile, the system (launcher, sight/tracker, guidance unit, tripod and missile)is the M220/M220A1 (FM 3-23-24)
6. The spotting rifle was the M8C. Since their might have been earlier units (to include an M8), I am tending toward "M8 series spotting rifle"
7. The Spotter-Tracer round was the M48/M48A1 and it was not related except for its cailber to the round fired by the M2/M3 series machine guns.
8. US vehicles included the M38A1C (http://en.wikipedia.org/wiki/Willys_M38) with a split windshield to accomodate the barrel, M151A1C with attachment points for the mount and seats for two crewmmen on the rear fender and the M825 which was the equivalent based on the M151A2. 
(http://en.wikipedia.org/wiki/M151_MUTT). Except for the Ontos and M274 Mule, no other platforms were standardized (in spite of field expedient mounts on M113's, naval patrol craft, etc in Vietnam). As fas as the rest of the world goes, the weapon could be mounted on virtually any light tactical wheeled or tracked vehicles, so the possibilities are endless. 
9. Give the designation of the Ontos (M50/M50A1) and its link -  http://en.wikipedia.org/wiki/M50_Ontos
10. Give the link to the Japanese Type 60 - http://en.wikipedia.org/wiki/Type_60_Self-propelled_106_mm_Recoilless_Gun
11. Ammunition. I question whether "High Explosive Antipersonnel" or "Cannister" rounds existed. If they did, who manufactured and who fielded them? Second, point out that HEP rounds were anti-material or "bunker buster" rounds with a secondary and limited anti-armor capability.
12. Add that a subcaliber device - the Rifle 30 caliber M9 - existed for training on restricted ranges or for low cost practice to keep the troosp sharp between Annual Service Practice.
13. I remember the "book" maximum effective range as 1100 meters, so I'm going to have to dig around the Net and would appreciate any pointers to references they may be aware of. 
Thanks for your help.

thread_title:  Possible Changes or Additions 

message: I am aware there is quite some confusion and disagreement regarding the ammunition type. I believe I have appropriately sourced the claim that it was renamed to 106mm to prevent confusion. If this is so, should not the references to "106mm" shells be renamed to 105?

thread_title:  The US Army did not judge the 105mm M27 to be a faiure 

message: Highly unlikely, the 106mm had long been replaced by Carl Gustaf in infantry roles and TOW in vehicle mounted roles, by the time Denmark went into Afghanistan.  — Preceding unsigned comment added by 188.177.179.122 (talk) 07:50, 12 February 2021 (UTC)
thread_title:  Danish use in Afghanistan 

message: The article mentions that the use of the .50 spotting rifle against personnel was discouraged, but not because there was a "law of war" that said cal .50 cannot be used against personnel. Actually, the Geneva convention forbids the use of exploding rifle rounds against personnel and most spotting rifle rounds are explosive in some way, to mark the hit, so the use of spotting rounds in any calibre against personnel is against the "laws of war". This was nevertheless ignored in WW2 by both German and Russian snipers.--Jarmo K. (talk) 16:58, 6 March 2022 (UTC)
