But he quite clearly said the shield would not be centered on, including the building of a new wall along the southern border and the authorities of federal laws.
That comes after President Donald Trump said last week he wants 2,000 to 4,000 National Guard members stationed along the entire 2,000-mile (3,200-kilometer) U.S. -Mexico Border.
"This will not be a mission to build a new wall", Brown wrote. There was a large spike in the number of attempted illegal border crossing into the U.S. from Mexico in the past couple of months.
Instead, California's national guard troops will combat transnational drug crime, firearms smuggling, and human trafficking.
California Governor Jerry Brown delivers his final state of the state address in Sacramento, California, U.S., January 25, 2018. "Illinois has not been requested to send troops".
Republican governors in the border states of Texas, Arizona and New Mexico have already deployed a combined 1,600 National Guard troops to the Mexican border in response to Trump's call for added staffing. Earlier under both George Bush and Obama, troops were deployed under Title 32.

Arizona recently deployed its first 225 troops to its border. It will not be a assignment to locate women and children or detain persons escaping violence and trying a better existence.
Brandon Judd, president of the National Border Patrol Council, the union representing agents, said Guard units could help by freeing agents to do more patrolling to search for smugglers.
Border Patrol Chief Greg Burwell said it's a challenge to keep tabs on all of it.
Pentagon spokeswoman Dana W. White told reporters Thursday that planners are looking at sending National Guard units that can assist with aviation, engineering, surveillance, communications, vehicle maintenance and logistics support.
Governor Brown was also very clear on exactly what the National Guardsmen won't be doing while they're at the border. Overall immigrant apprehensions on the border last year were as low as they've been in almost 50 years (and 85 percent of the apprehensions occurred outside of California).
"I don't suppose it's a partisan downside or an id downside", he talked about. U.S. Customs and Border Protection however says apprehensions in the last six months fell by about 34,000 from the same period last fiscal year.
