Terming Bhagwat's comment as "anti-national and demeaning", CPI-M leader Sujan Chakraborty demanded his arrest.
Just giving lectures in rallies and television will not serve any purpose," he said.
However, in an attempt to defend Bhagwat, the state Bharatiya Janata Party said he did not compare RSS with the Indian army but referred to the extent of their preparedness and patriotism for the country.
"What he meant was the RSS activists would be prepared first in case of a calamity. They are disciplined and patriotic. They follow a rigorous training routine everyday so they would easily prepared," argued state BJP president Dilip Ghosh.
Bhagwat's statement in a gathering in Muzaffarpur on Sunday courted massive controversy, as he claimed that in case of a war, the Indian Army would take six months to prepare whereas RSS volunteers can get prepared in three days to fight on the borders against the enemy.
