Guy shooting women and children from helicopter in war related movie

Probably pretty famous movie, probably easy to find but I don't like war movies so I don't wanna search it myself.

I remember seeing this scene where male soldier is sitting in flying helicopter with few other people. He uses the build-in MG42 looking gun (not sure at all) to gun down non armed females probably some males and children too but not 100% sure. It seems to be "legal" or "acceptable" even thought his allies in the huey are looking at him disgusted and if I remember correctly one of them asks "Do you like killing women and children?"

I don't remember 100% but seemed like the gunner had fun and seemed to enjoy it enough to do it even thought it was socially unacceptable inside the huey.

EDIT. The non-armed victims where running in open field either away from helicopter or towards it, the helicopter moved pretty fast so the gunner probably didn't kill even 10% of em.
