My last comment was a highly positive one; in this one, I need to throw just a bit of the negative side. It is not negative towards Army 12A Engineers, but against the ones who control their movements and work.
I have lived in Puerto Rico for 3 years and the island of Vieques at one time was almost completely controlled by the Army. They deserted it but left many remnants of their being there. Many unexploded bombs are found day by day.
It is my opinion that the U.S. Army should have teams of these engineers on that island getting it completely safe for civilians.
Any thoughts on this?
That’s pretty crazy, Greg. Hopefully, they will send in some Engineers to fix things.
The Army Corps of Engineers is one of the most important to the infrastructure of the Army. The MOSs under this field provide services vital not just to the military, but the civilian world as well. Disposing of hazardous materials benefits EVERYONE! The building of roads and bridges make travel and transportation more seamless and safer. And of course, being able to neutralize and disarm the enemy is at times better than engaging the enemy in combat. Allowing a more peaceful end to situations with as few casualties (civilian and military) as possible.
These posts would be great for young people to read. They may give them ideas for goals for later life.
The Army Corp of Engineers handle many aspects of resources in the United States that many people do not realize they handle. I consider an area that I used to live at…Lake of the Ozarks in Missouri. This lake has a dam that supplies almost all the electricity to St Louis, Missouri. It is all managed by the Army Corp of Engineers.
If a young person has a desire to be an engineer, but does not have the funding to go to college, it makes great sense to join the Army, follow the protocol and raise to where they can become a 12A Engineer Officer.
