If the enemy were a conventional force, they would have bombarded the shield with artillery or shot lasers at it from orbit where Wakanda had no hope of retaliating.
Thanos's forces were retarded too, but since all they wanted was a distraction so they could steal the stone, they can be excused for limiting their resources to a bunch of dogs that were, let's be honest, probably clones.
With a force that small, taking up a position in an empty field with no fortifications meant they were going to be surrounded. Period. It was a suicidal move no matter who they were fighting. Hell, it would have been magnitudes worse if the enemy had air support like the Chitauri, because then they'd be surrounded on every side but the soft ground where their guts were going to spill out - and that's assuming Thanos didn't have some sort of burrowing weapon, which he probably did.
They weren't merely unprepared, they were actively throwing the fight. Their position was designed to be overwhelmed and defeated. There was no strategic or tactical advantage to being in that open field. There should have been some manner of weaponry in a fortified position somewhere.
Also, opening the shield doesn't create an easy to kill funnel if they can just rush in and surround you anyway. Look at what happened in the movie. They were at first concerned they might be surrounded, so they lowered the shields, and then they were surrounded.
It's a matter of numbers. It was stupid in every conceivable way and there's not any excuse. It doesn't matter if it was the Chitauri or if it was the Care Bears, it was still suicidal and a losing position.
