The ACOE were even part of Patton’s fast army in Europe and they were building forts, bridges, roads for the army to roll through and we couldn’t do a damn wall? Hopefully there will be machine gun turrets added..
There’s a big difference between the Army COE and Army combat engineers that actually get their hands dirty building and destroying in support of combat operations. The (domestic) COE is essentially a custodial agency made up largely of civil service workers under the supervision of a handful of Army Engineer officers. Whatever construction that falls under their purview is almost always contracted out.
