Tank cant work in high altitude and mountainous terrain so probably atgms, manpads against the chinese light tanks if talking about bunkers then probably the isreali bunker busting missile we have cant remember the name but something 300 it was.
I never said to demoralize the stryker I just said they are two different vehicles for different type of roles BMP 2 has a protection armour of against 34 mm and stryker has armour protection against of 14 mm, I said they are two different vehicles.
Both were made for different role while the striker are mostly single v hulled unless provided with extra protection with double v hull and extra ERA packages. Bmp 2 has a slight better armour but it will dependably mostly on upgrade of electronics and able to see enemy first.
The spriggan Missile is a capable ATGM's with a 152 mm and 1300 mm RHA thermobaric warhead it is a capable weapon despite developed in 80's capable of hard kill against most target's
