Without Googling can you name these two weapons?

Cannon & Ball?

Mortor and rocket launcher

Not sure about the first one or second one either.

Second one is a mobile scud launcher.

Is the first a kind of Gatling gun?

Earliest version I've heard of was Korean, back in the 1500 or 1600s? A multiple launcher that sharp rocket-propelled arrows or spears, I think.

I think they are both similar to each other and known as Stalin organs...

Probably wrong but a missile launcher and anti-enemy aircraft rocket launcher.

Not sure the exact names but they are rocket launchers

PewPew and BangBang

Or rocket depending on your view

Katyushka and nebelwherfer

Both same mortar

rocket launchers

Sword and spear

Yep.

No clue

Nope

The bottom one reminds me of the ancient Korean hwacha mixed with a anti-aircraft battery. And the first one reminds me of a howitzer.

Types of multiple rocket launchers?

Nope

Steve and Pete.

Toilet roll cannon and old train track launcher..so the answer is no

Top one looks like a Gattling cannon the bottom looks like a missile launcher 😘😘😘
