Wow,
Glad your brother wasn't seriously hurt or killed. I hope your brother is put in a less dangerous position!! May
Well, that is his job, to find IED's just not to get blown up by them. He is a 21 Bravo which is and Engineer, in other words he blows things up. The intent is not to be IN the explosion though, lol.
If they didn't go out in those mine resistant vehicles to find them a lesser armored vehicle or Iraqi citizens would likely be the victim.
He would tell you he is just doing his job.
