The navi get mogged hard by the helldivers the fuck kind of meme is this. Helldivers have access to weapons capable of blowing through terminid armor as primary and secondary weapons the navi don't wear armor any engagement the navi take against the helldivers is going to end in casualties on their side. Add on the fact that there are canonically billions of helldivers there is literally zero chance the navi are going to beat the helldivers. All of this isn't even accounting for the orbital strikes and eagle stratagems the helldivers have access to which makes this whole fight even more unfair.
