Here is some information about this stickman

Phase 1
He was in war while he was 35 years old and stayed in war for 10-20 years, which now made him like 55 years old, he fought 15 wars and never got injured but in his 1st war, he got shot in the eye but is still alive from that, now he just wears a eyepatch to cover up the shot eye and also he retired from the military but he still kept his helmet just to remember his military history.

Phase 2
Whenever a loud sound like a gun or a firework it triggers his military memory, basically he is like Fliqpy and Flippy and when the loud shot and boom is heard he starts to remember the war he goes to and he goes out of control grabbing his Ak47 in his home and just starts killing, a way to calm him down is by giving him headphones and listening to music so it won’t trigger his military memory anymore
