Also former infantry: To expand the point, in US Army doctrine, an obstacle has one of four effects, block, turn, fix, or disrupt.

Typically, you use obstacles in engagement area development as part of a defense. An obstacle that's not observed isn't valuable because it's easy to circumvent. You can probably use a bulldozer (guessing, I was light infantry, not a tanker) to breach the dragon's teeth relatively quickly so the obstacle doesn't have the intended effect. However, it's much harder to breach the dragon's teeth if someone is shooting at you. Now you need an armored bulldozer, or enough suppressing fire to cover the breach.

The way Russians teach it, obstacles and mine fields just buys you some time. Crucial time to put your pull your reserves to the critical areas, sight in your artillery or call in air support. Even worse, it buys you very little combat time for a lot of preparation time.

However, on top of the shame for what Russians are doing in Ukraine, the shame for how they are doing it is almost as disgracing.

Sounds like a job for something like Python if they are unanchored. Or an AVRE.

You do have to be careful with these systems, they like to go boom:

Where is Marvin Heemeyer when you need him.

Or a remote-controlled bulldozer. (Though that could be jammed...)

The idea is that for every 20 tanks the enemy has there's probably one RC bulldozer. Without the obstacles they would quickly advance over few hundred meters, now they are forced into a bottleneck, perhaps giving you just enough time to bring in the ATGM team.

I bet those autonomous programable excavators and bulldozers are right now making a killing in UA.
