Semi truck trailers or metal shipping containers aligned end-to-end can provide a temporary border barrier wall with a top surface for troops and equipment to move around, observe, or defend from an elevated position.

(Excerpt) "President Donald Trump said Thursday [4.5.2018] that he wants to send between 2,000 and 4,000 National Guard members to the U.S.-Mexico border to help federal officials fight illegal immigration and drug trafficking...

[This initial deployment] is lower than the 6,400 National Guard members that former President George Bush sent to the border between 2006 and 2008.

Trump said... 'we’ll probably keep them or a large portion of them until the wall is built.'”

On Topic:

The essence of the steel-and-concrete hybrid system is that steel panels are used on the outside surfaces of wall cavities as forms for the cast-in-place concrete walls. The steel forms remain in place permanently to contribute reinforcement and speed construction time. Higher and higher modules of steel forms can be assembled, and concrete poured into the cavities, without waiting the usual period for the previously poured concrete to cure.

The usual array of professional consultants are responsible for producing drawings and specifications that define the requirements for construction in specific locations.
