There are no "shootouts". There are standoffs sometimes (think once a year if you want to define regularity) due to the loosely demarcated Line of Actual Control (LAC) between India and China. It's usually a melee. Even the recent escalated incident wasn't a shootout. There are agreements between Indian and Chinese governments that prevent usage of firearms in standoffs like these.
> What’s happening along the Himalayan border is an unusual kind of warfare. As in the brawls last month, Chinese and Indian soldiers fought fiercely without firing a shot — at least that’s what officials on both sides contend. They say the soldiers followed their de facto border code not to use firearms and went at each other with fists, rocks and wooden clubs, some possibly studded with nails or wrapped in barbed wire.
