In Grand Theft Auto: V, what wanted level does the player receive if they enter Zancudo Army Base north of Los Santos?

In Grand Theft Auto V, the player receives a wanted level of 4 when they enter the Zancudo Army Base north of Los Santos because this military facility is highly guarded and trespassing on it is considered a serious offense. The base is restricted and off-limits to civilians, so anyone caught within its premises is immediately perceived as a threat and subject to swift and aggressive response from the military forces stationed there. Hence, the high wanted level of 4 is assigned to represent the severity of the situation and the strong enforcement effort to detain or eliminate the intruder.
