San Jose police said they are as prepared as they can be for Super Bowl 50, which will be played at Levi's Stadium next month in neighboring Santa Clara.
Officers spent Thursday training, including an active-shooter drill.
The San Jose SWAT team, known as the MERGE unit, typically trains for emergency situations one week every month. But this month, the special unit participated in emergency drills everyday to be mentally and physically prepared for the week of Super Bowl events.
"Being in that constant state of readiness for 12 hours, then going home and having limited time with their family, and getting right back at it for 12 to 13 hours is going to be a grind over the course of 10 days," San Jose Police Lt. Jason Dwyer said. "But we're ready."
The department's Bear Cat armored vehicle will also be stationed at large events in San Jose beginning Sunday. The vehicle will also be stationed at the airport.
NFL players or tourists will also likely see Jerry, a 2-year-old dog who is trained to sniff out explosive materials. Intelligence officers will be monitoring cameras throughout the city, and communicating with other law enforcement agencies on a secure network.
"The officers are ready physically, mentally and based on the training they're ready for anything that comes up," Dwyer said.
Police said last year in the week leading up to Super Bowl 49 in Arizona, there were about 15 to 20 threats on the big game every day. Police said there are currently no known threats on Super Bowl 50.
