The first video should be a firing range test of their newest mini tank being shot at under controlled circumstances on a firing range. If that video does not come up, click the link marked "Badger Bullet Test" and watch the fun.
The next video in the que shows a pair of explosions including a fragment grenade placed by the driver's access hatch.
If you're not watching Howe and Howe Tech, record it.
