Members of a SWAT unit put in a request to see a field test of a fully functioning Badger, the world's smallest armored tank. But after the last blast test blew its tracks to pieces, the Howe brothers are left scrambling to resurrect the Badger. Adding to the time crunch, the crew at H&H is still working on building three Subterranean Rovers for a mining company and they're way behind. And with so many projects in full swing, the twins still need to find a shop big enough to fit their growing business.
The US Army asks the Howe brothers to modify their most famous vehicles, two high-speed tanks called Ripsaw MS1 and Ripsaw MS2. Ripsaw MS1 is a remote controlled tank and Ripsaw MS2 is a manned version. Now, Mike and Geoff must make Ripsaw MS2 operate remotely as well. In the middle of it all, Mike, Geoff and their amazing Ripsaws must star in a TV show called "Popular Science: The Future Of..." The publicity is great, but the rigorous test-drive for the TV cameras ruins the wheels on MS-2 and the twins have to order new ones. Will the new wheels arrive on time? And will a last minute technical glitch jeopardize H&H's all important military contracts?
Geoff and Mike get the idea to build a miniature version of the Ripsaw, H&H's ultra-fast military tank. They call their newest invention "Mini-Rip" and market it to the general public as a recreational vehicle. The twins hope to finish Mini-Rip just in time to debut at the annual Grass Drags, a large motor-sports event in New Hampshire. Meanwhile, H&H gets an order for three more SR-1 Subterranean Rovers and Geoff has to go down to Ft. Hood, Texas to show off the Ripsaw's amazing abilities in hopes of getting more contracts with the Army. Managing several large projects at once puts a strain on the brothers' relationship and jeopardizes the completion of their latest and greatest machine.

The Howes have a new shop, a new female welder, and a crazy new idea that might just revolutionize fire fighting. A request from the Army has the team creating a new set of Ripsaw tracks for the sole purpose of blowing them up in as many ways as possible.
The Howe & Howe team almost breaks their fire-fighting robot preparing it for testing with the fire department. Mike's Ripsaw weapons demonstration for the Army is a huge hit and hatches the idea for the Howes' next big R&D gamble.
Mike and Geoff are underway on their new amphibious tank, but a Vietnam Vet's email takes them on a detour to build an all-terrain wheelchair. The team's competition to build prototype ballistic armor for the tank has an explosive ending.
The Howes take on building and testing a prop vehicle for a major motion picture. Meanwhile the crew moves forward on the Riptide amphibious vehicle, including a dangerous test of its escape hatch system underwater.
Time is ticking on the Riptide project. The Howe & Howe team bears down, but their first test with the Riptide is disastrous. But it's not all bad news. Mike's seemingly tangent project -- a turret for the Riptide -- is an explosive success.
The team has to scramble to fix the engine on the amphibious Riptide before it can be presented to the Army.
