Probably a movie from the 80s or 90s.
The scene I remember is
The film begins with a scene where a hostage situation takes place in a certain building.
The protagonist, a police officer, is handed a shotgun by his colleague, climbs on top of a patrol car, and climbs up a ladder to solve a hostage situation.
The he and his son are looking at fishing gear, and the son accidentally drops them all on the ground. he says something to his son(God damn it), wife who saw it told not to say too much.
and then the whole family goes camping.
The next day, wife and son were on the boat first, and when they started the boat, it exploded.
While looking for the culprit in the boat bombing, he fight with a gangster in a certain town.
During a car chase, he kills a gangster with a machine gun displayed on a glass wall.
After that he go into the mountain
(I think the content from this point is similar to Rambo 1)
The town sheriffâs younger brother was killed by the main character and heâs pissed.
They even called in the National Guard to try to find the hiding in the mountains.
He sneaks into a National Guard camp in the middle of the night and steals ammunition and supplies.
They get discovered, engage in a fight, and then run away to mountain
At the end of the movie, the National Guard and the sheriff ascend surround the mountain,
It ends with a close-up of the main character firing a machine gun.
(The type of machine gun seems to be M60 or similar to MG34.)
