In all seriousness, digging tunnels is a military tactic that gets some use sometimes. The Russians have done it in the southern part of Avdiivka. I haven't heard of a case where militaries used an actual tunnel boring machine, though.

Tunnel boring machines are not just extremely expensive, they're also extremely bulky and highly visible when on top of the ground. If you ship one to where you want to start your tunnel, there is a high risk that enemy intel will spot it, ruining the surprise.

The actual digging is extremely slow, meaning there is no way of knowing whether the tunnel will even still have some tactical use when you're done.

Once you emerge on the other side, it won't be long until the enemy notices your exit and does something about it, like bombarding it, stationing troops there or sending something of their own back through the tunnel. That means even if you succeed, you only have a very short window to do something with your tactical advantage, and said something will very likely be a suicide mission.

Tunneling through the loose mud of Ukraine would not be easy. You can do it if you send a work crew after the machine to immediately build strong walls behind it, but that would be even slower and more expensive.

All in all, it would just be more useful to use either much smaller and shorter tunnels that don't use tunnel boring machines or utilize some form of artillery or drones to achieve the desired effect behind enemy lines.

Adding that tunnel boring is really noisy. Russian seismic activity sensors should pick it up and locate long before they get even close

You can mask the noise with nuclear strikes.

A community for your defence shitposting needs

Rules

1. Be niceDo not make personal attacks against each other, call for violence against anyone, or intentionally antagonize people in the comment sections.

2. Explain incorrect defense articles and takes

If you want to post a non-credible take, it must be from a "credible" source (news article, politician, or military leader) and must have a comment laying out exactly why it's non-credible. Low-hanging fruit such as random Twitter and YouTube comments belong in the Matrix chat.

3. Content must be relevant

Posts must be about military hardware or international security/defense. This is not the page to fawn over Youtube personalities, simp over political leaders, or discuss other areas of international policy.

4. No racism / hatespeech

No slurs. No advocating for the killing of people or insulting them based on physical, religious, or ideological traits.

5. No politics

We don't care if you're Republican, Democrat, Socialist, Stalinist, Baathist, or some other hot mess. Leave it at the door. This applies to comments as well.

6. No seriousposting

We don't want your uncut war footage, fundraisers, credible news articles, or other such things. The world is already serious enough as it is.

7. No classified material

Classified ‘western’ information is off limits regardless of how "open source" and "easy to find" it is.

8. Source artwork

If you use somebody's art in your post or as your post, the OP must provide a direct link to the art's source in the comment section, or a good reason why this was not possible (such as the artist deleting their account). The source should be a place that the artist themselves uploaded the art. A booru is not a source. A watermark is not a source.

9. No low-effort posts

No egregiously low effort posts. E.g. screenshots, recent reposts, simple reaction & template memes, and images with the punchline in the title. Put these in weekly Matrix chat instead.

10. Don't get us banned

No brigading or harassing other communities. Do not post memes with a "haha people that I hate died… haha" punchline or violating the sh.itjust.works rules (below). This includes content illegal in Canada.

11. No misinformation

NCD exists to make fun of misinformation, not to spread it. Make outlandish claims, but if your take doesn’t show signs of satire or exaggeration it will be removed. Misleading content may result in a ban. Regardless of source, don’t post obvious propaganda or fake news. Double-check facts and don't be an idiot.
