well let this be a warning. After deploying your HT dont deploy anything right after that can't take a hit from Su-51 or GW tiger cause theres a glitch that happens where the unit you deploy right after despite being no where near your HT dies instantly.

In my case after deploying my tiger I i had my Su-51 follow up after a second or two when tiger has engaged the enemies with enough distance and right when I did that my Su-51 died the moment it spawned despite being a good 3 units away
