Well, armed humvees pretty much qualify as mech infantry, if they don’t have to worry about IEDs they don’t need to use MRAPs. On the other hand, it would not surprise me at all if they DID try to employ IED as a tactic. Don’t think it would work for them, what with us the home team.
I’m behind the times.
113’s and Bradley AFVs were more in my mind. I understand the Bradley is essentially gone.
