I'm not a physicist and obviously the Star Wars universe does not follow the laws of physics BUT.....

My friend and I were arguing over how easily the Ewoks were able to route professional stormtroopers, "Palpatine's best men." One part we disagreed on was how easily two large tree trunks took out an AT-ST. I understand it's a scout vehicle, but still, according to this source, they weigh 25 tons. Couldn't a AT-ST withstand the impact of two colliding trees? I'm pretty sure an Abrams tank could withstand that force no problem.
