It’s clear you aren’t Iranian or understand the country. Kurdistan border is porous due to its rugged terrain. This allows sleeper cells to infiltrate for hit and run attacks. MRAPs aren’t just for mines, they are protections against heavy arms fire and RPGs as well which are very easy to find in Iraq after years of war or be supplied by Mossad in Iraq.
So yes traveling in Toyota trucks and Aras trucks is not smart. At the very least an armoured truck to protect against small arms fire or an ambush.
