I love this mod, hoping the author updates it. In the meantime, you need to adjust the 'life' values of the 9k115, 9k135, and bgm-71 to something greater than 1.0. I use 1.5 and it works great. Open the mod's folder and find the 'Entry' folder. Inside is the Lua entry files for all the units, the 'life' values are found around line 30 and default to 0.08. Change to 1.5.
