Latinism, etc.[edit]

Your effort to delatinize the language is commendable, however, considering the requirement for the material to be encyclopedic, to the point (non-literary and non-colloquial), my corrections were intended to achieve just that and to make it more in agreement with the USN Diving Manual. In all other respects, I would agree with you and stick to the Orwell's trusty Politics and the English Language, --Bo Basil 17:14, 28 February 2007 (UTC)[reply]

Multiple Wikilinks[edit]

I feel that this (good) article is overlinked to simple terms such as scuba diving, frogman, open circuit and rebreather. I guess the correct path lies somewhere between the two edits. WP:MOS ([1] and [2]) suggests that one appearance on a screen is sufficient. Finavon 11:17, 10 June 2007 (UTC)[reply]

  • There can be much text on a screenful, and it is tedious to have to search and search for the only link within miles to a word that occurs several times in a screenful. Anthony Appleyard 12:15, 10 June 2007 (UTC)[reply]
- made easier if there are not a host of other links! I've restored the only correction I feel strongly about - avoiding the disambiguation page for diver. Finavon 13:44, 10 June 2007 (UTC)[reply]

FBI and scuba diver info[edit]

  • I inserted a link USA scuba diver information said to have been handed to the FBI, and it was deleted at 06:52, 1 February 2008 with remark "Undid link to blog site added by Anthony Appleyard (talk) - unacceptable per WP:EL)"); but WP:EL says that links to blogs are "Links normally to be avoided", and the matter described ("After 9/11 the F.B.I. asked the nation's largest scuba diver certification organizations to turn over the records of all divers certified since 1998. This is now done on an annual basis.") is an important matter concerning privacy of information and freedom to scuba dive, and if the only online ref to it is a blog, then the blog will have to be the ref. Anthony Appleyard (talk) 10:17, 1 February 2008 (UTC)[reply]
Sorry, I deleted this again but didn't notice this message prior. It is hard to understand why an exception should be made to allow an EL to a blog because it is the only available reference making a particular claim. In most cases that would be a very strong additional condition deciding not to allow it.Professor marginalia (talk) 07:06, 8 February 2008 (UTC)[reply]

Copy editing, sourcing[edit]

This is a really interesting article with pretty in-depth detail, and a good example of how wikipedia can be a great resource for information about topics of special interest that most general encyclopedia's can't or won't include. Some copy editing will be useful, however, to document claims in it to particular sources. The article has some fact tagging already, and there are other places where a cite seems needed as well, places that aren't tagged yet. Unfortunately many parts of the article appear to be WP:original research, though most of these may indeed have references, and could possibly be sorted out once the citations are identified. For example, take this passage: "In most scenarios nowadays #1 or perhaps #2 is likelier, but in war or semi-war conditions or where there is a risk of terrorism #3 may be likelier than usual. A police-type technique that is reasonably safe on land may be risky to a scuba diver. The document nlsn leans strongly towards #1, and discusses only non-lethal weapons. But in war and semi-war situations there is more risk of #3 and the choice may be for lethal weapons." So far no source has been identified for the claim to "more risk of #3"-which is a real concern since it is contrary to what's written in the source that is identified, the nlsn. That's an example where a source is needed; if there isn't one, the claim can't be made in the article. My thought is to work through section by section, adding inline citations where they're called for, and fact tagging where necessary. Professor marginalia (talk) 16:04, 8 February 2008 (UTC)[reply]

From the "Police-type or riotsquad-type non-lethal weapons" section:

"Judo throws and similar are unlikely to work in zero gravity, including underwater."

This suggests that "underwater" is zero gravity, which, if true, would make it hard to understand why a rock thrown into a pond will sink to the bottom. In any event, the likely disadvantage in trying to use "judo throws" underwater would be the lack of a hard surface to brace against when lifting or off-balancing the target, and of course the lack of a hard surface to land (if not slam) the target against.

New discussion

OK, I'll start. Referencing Wikipedia:External links:

  • The external links under contention fail to meet the relevant criteria for what should be linked, specifically item 3 (neutral and accurate material that cannot be integrated into the article due to copyright) and item 4 (meaningful and relevant content not suitable for inclusion). The content of those pages could be integrated into this article, and the content is suitable for inclusion. Therefore, the links fail the "what should be linked" criteria.
  • The links do meet one or more of the criteria for links to be avoided:
    1. the sites do not provide a unique resource beyond what this article would contain if it were featured.
    4. The links were added for the purpose of promotion. This is particularly true for the Kongsberg link, which was added by a serial spammer contributions with a conflict of interest.
  • Links added due to a conflict of interest should be deleted. The only reason I came across this article in the first place was because I was cleaning up the mess left by this spammer in several other articles. The spammer has been warned but evidently pays no attention.

Now, all that being said, I admit it's possible for a spammer to submit a link that actually enhances an article while meeting the spammer's purpose of promoting his company. I've seen it happen in other articles, where a spammer posts something, someone else comes along to clean up, and the editors restore the link because it seems useful. The information in those links seems like it could be obtained from other sources, though. The article could include the informative content of those pages and do away with those external links. =Axlq 16:37, 31 May 2008 (UTC)[reply]

Rebuilding this article[edit]

This article has had much of it removed recently and much of the content could be suitable for a non-wikipedian site. Most of the removed content was speculation and uncited information. Clearly the original writer was knowledgeable and had a great interest in the article however. If a dedicated person interested in the subject wanted to take the previous version of the article and rebuild it, it could be useful.

Some of the content removed could be introduced into the article and many of the dead links could find a new citation. Perhaps a part of the article could warrant their own pages? - AH (talk) 15:00, 9 April 2020 (UTC)[reply]

@AttackHelicopter51:, A part of the problem is that the scope of the article is poorly defined, making it difficult to identify what content is appropriate, so it has ended up as a coatrack for a wide range of tangentially related information and trivia. Part of that problem is the title. It refers to "frogmen", which is a poorly defined term, but commonly understood to be tactical military or paramilitary scuba divers. However the article content extends to civilian and non-political criminal activity, and defense against non-diving marine related coastal incursions. The first objective should be to decide on a better title and define the scope, and to ensure that the title matches the scope. I have not been able to do this. it is quite possible that we need to split the content into more than one article, each with a well defined scope to suit its title. Do you have any constructive suggestions? I would welcome one that omits the word "frogman" and uses a more clearly defined term, whether the scope is thereby expanded or contracted is less important. · · · Peter Southwood (talk): 06:28, 24 April 2020 (UTC)[reply]
@AttackHelicopter51:, repinging in case you missed the first time. · · · Peter Southwood (talk): 07:03, 30 April 2020 (UTC)[reply]
Thanks for reping, For some reason I didn't get the notification for the first ping. I think the article should mostly concern military activity, as frogmen is near unused in the civilian world. But I also welcome a article without frogmen, perhaps a title relating to espionage. - AH (talk) 08:19, 30 April 2020 (UTC)[reply]
@AttackHelicopter51:, We need to cover the general case in a rename, to include as much as possible of the salvageable content, but if there is enough suitable content a more specific article can be created by splitting it out later, and espionage is definitely within scope. Please feel welcome to add suitable content at any stage. Cheers, · · · Peter Southwood (talk): 17:47, 16 May 2020 (UTC)[reply]

Suggestions for new title:

  • Defense against diver incursions. This would restrict the scope to actual divers, but include industrial espionage, poaching, theft and vandalism of historical sites, as well as military actions, espionage and sabotage. It would also exclude surface swimmers, which might be undesirable. · · · Peter Southwood (talk): 06:50, 24 April 2020 (UTC)[reply]
  • Defense against swimmer incursions. This would expand the scope to include both divers (underwater swimmers) and surface swimmers. A bit vague about whether divers using diver propulsion vehicles would be included, but the scope can be defined to include them as in many cases the occupants would be swimming at least part of the time. · · · Peter Southwood (talk): 06:50, 24 April 2020 (UTC)[reply]

Discussion of article scope:

The titles suggested above ("Defense against diver incursions" or "Defense against swimmer incursions") are fairly wide in scope. It is likely that such an article would need to be split at a later date as the content exceeds the recommended limits, and some types of content are likely to be more accessible than others in terms of reliable sources. This is probably a good thing, and in any case not yet a problem. · · · Peter Southwood (talk): 06:58, 24 April 2020 (UTC)[reply]

Unless there is any objection within the next week I will be renaming to Defense against swimmer incursions · · · Peter Southwood (talk): 16:38, 16 May 2020 (UTC)[reply]

No objections have been posted, so will be making the change as uncontroversial. · · · Peter Southwood (talk): 08:58, 3 July 2020 (UTC)[reply]
