#6 wth the top of #4
I don’t think breaching any of these prototypes is going to be a difficult proposition.
The ones with the see-thru bottoms are failures.
Launch a weighted rope over the top and down the other side. Tie it around the see-thru support and you can scale over the wall easily.
The ones with a flat top fail also as a grappling hook can attach to them.
The ones with the rounded top and solid walls are best to prevent easy scaling
Still, they all need reverse razor wire at the top facing Mexico. It's worked in California, and that "wall" is just a double fence with a road between with lights and sensors. It cut illegal crossings by some 95% and the reason that the illegal crossings became such an issue in southeast Arizona that has nothing but a 5 foot barbed wire fence or nothing in that area.
Remember the Minutemen? I was one of them and drove I-8 from San Diego out to Tuscon and down to Tombstone to stand watch. I've seen and contrasted the differences and what has worked and what is needed.
Contrary to popular belief, we don't need such huge barriers all along the southwest. There are such large expanses of deserts that are miles and miles from the Mexican border that are too far from staging areas where the illegals can meld into. It would take an entire Army logistics division to get them across that wasteland. Look on a map.
That said, there are areas in eastern Arizona and parts of New Mexico that need such barriers in certain areas. The main problem is Texas. Because they have Mexican towns so close all along their border, that's where we should build first.
Second from bottom right. Do we have a estimated cost for each?
#4 (top right) looks good to me...
I prefer the one with the barrel atop it. Very difficult to get around or over a barrel atop a wall.
I like #4. Add Claymore AP mines along the top and it’s perfect.
#6 and 7 should only be considered if those metal posts are electrified
Wall porno! Love it.
The wall on the lower set of pics and second from the right side with something like a culvert on the top looks like a winner.
The culvert would eliminate most schemes to crawl over the top.
Also, our border patrol agents can observe what is happening on the other side of the wall.
