The U.S. Army developed an experimental 155mm truck-mounted howitzer, called the Brutus.

The photos of experimental truck-mounted howitzer were published on the Facebook page of the 75th Field Artillery Brigade (artillery brigade in the United States Army) on 26 October.

The Brutus is a 155mm truck-mounted howitzer for increased mobility and enhanced firing capabilities. Experimental 155mm howitzer installed on an FMTV 6X6 truck chassis.

Howitzer is capable of using a wide range of ammunition for deployment against protected and unprotected targets, to create counter-mobility obstacles to block the manoeuvres of enemy armoured forces and to obscure or illuminate an area.

No further details on the type of howitzer have been released.

The U.S. Army interested in new, more mobile, lightweight artillery pieces.

Early, Army’s officials showed interest in 105mm Mobile Weapon System (105MWS), also dubbed HAWKEYE by AM General, consists of one 105mm cannon mounted at the rear on HUMVEE light tactical vehicle chassis. Maybe U.S Army is also interested in upgrades for or modification to its existing weapons, especially lightweight 155mm cannons, or various types of self-propelled guns.

Having that kind of firepower on-call is immensely important for the Army’s light infantry, especially when conducting independent operations where they might not have the guarantee of support from other services or even other elements within the Army.

Brutus because it is supposed to kill Caesar (the French truck-mounted howitzer)?

It's the Hummer's 105mm big brother

That reminds us of the experimental Bobcat 105mm SP gun.
It was based on the 1950s vintage, experimental, Bobcat Armoured Personnel Carrier. It absorbed massive amounts of R&D dollars, but never produced a reliable chassis for the Canadian Army.
They built one SP prototype with a 105mm howitzer in a high-sided hull.
Every time it fired, it landed in a different grid square!
Hah!
Hah!

Will be interesting to see what BAE offers the US Army in this space.

I remember seeing a Toyota pickup with a 105mm howitzer and I wasn't sure if it was some official modification kit (Aftermarket "upgrade"?) or just another one of those ridiculous things an insurgent cobbled together. Or if it would even work.

It was low-resolution and meant to be a meme more than anything, so for all I know it could have been Photoshopped as well. Anyone know what I'm talking about?

EDIT: It just occurred to me, CAESAR is a L/52 howitzer. I can't tell easily due to foreshortening, but doesn't Brutus appear to be carrying a L/39? Does that mean they put weight into other things like protection?

EDIT 2: Hmm, now I can't tell. The second image suggests it might be a L/52, but I can't see the muzzle.

Word is that the gun is Mandus Group's soft-recoil 155, which can take either 39- or 52-caliber tubes.

Soft recoil? Like a 155mm version of the XM204?

Yes, it is a fire out of battery weapon.

Not much word if and how Mandus group has resolved the longstanding problems that come with it...

I suppose Course-Corrected Fuze technology might help.

What problems existed with it, exactly? I know someone who worked in artillery who said that recoil was actually a good thing, though their explanation for it was a bit murky.

Test firing of the Brutus, an U.S. Army experimental 155mm low-recoil self-propelled howitzer mounted on an 5-ton FMTV ( Family of Medium Tactical Vehicles) truck at Joint Base Lewis-McChord, Washington, Jan. 17, 2019.

Doesn't look like it's firing out of battery, but maybe the effect is too quick to see with the naked eye.

Slowing down the vid shows that there is no "out of battery" when fired.

IMHO it's due to such a small charge being used to launch the practice round.
