>>64015792 (OP)Please. Stop asking this stupid question about everything. Just because thing is not a perfect counter to other thing does not mean it's not viable on the modern battlefield.
A foxhole might not be that effective at stopping an FPV from hugging you but if it hits your buddy in the next hole over instead you should be ok. He's in a hole, you're in a different hole, shrapnel probably isn't going to get you.
