"The issue is not about divisions, the issue is about regiments. The regiments include divisions, the number of regiments defines the number of divisions," Rogozin told reporters on the sidelines of the St. Petersburg International Economic Forum (SPIEF) when answering a question about New Delhi's plans to purchase several S-400 division sets.
The regiment set of S-400 comprises two brigades that include up to 12 launchers.
SPIEF, a major global platform for communication between business representatives and for the discussion of crucial economic issues, kicked off in Russia’s St. Petersburg on Thursday and will continue through Saturday. The Sputnik news agency is an official media partner of the forum.
