The Russian military isn't necessarily known for subtlety. The phrase "bigger is better" certainly seems to be alive and well in their strategist's minds. From gargantuan tanks to massive airplanes to huge artillery pieces. Even the equipment used for fighting among the buildings and along the streets of a city are bigger. Such is the case with the 203mm obr 1931 Howitzer, now available for Flames of War.
This monstrosity of a gun weighed 19 metric tons, requiring it to have its own tracked chassis to move it. It fired out 203mm shells that weighed in at 100kg each. It could reach out and touch the enemy at 18km, but was often used as a direct-fire gun at point-blank range. And now you can add it to your Flames of War Forces. I'm sure your enemies will be happy about that. ;)
