The Trump administration has awarded contracts to build four border wall prototypes using non-concrete "other materials," US Customs and Border Protection announced last week.
The contracts came a week after the administration announced four companies that will build prototypes of concrete border walls. In all, the eight prototype walls will cost about $3.6 million.
One of the four companies selected to build the non-concrete prototypes is ELTA North America Inc.
