There are 3 types of rocket launchers in KS mod:
1. Light
2. Medium
3. Heavy
In those categories are listed these types of launchers:
1. Light: RPG-2, RPG-7, Zolja: those are man portable carried launchers, with smaller penetration values but many soldiers have them(some of them carry only one rocket and are disposable).
2. Medium: Strsljen, HJ-8(portable or movable tank busters)
3. Heavy: Maljutka and Bumbar: heavy tank destroyers
All of them have nice rocket effect which maybe looks nice but reveals positions. Be advised when using it.
