Soon after the House met for the day, Trinamool Congress leader Sudip Bandopadhyay raised the army deployment issue, saying the state government was kept in the dark on the matter.
The claim was refuted by Defence Minister Manohar Parrikar, who dubbed it as a routine exercise held annually since past many years.
Opposition Congress and Trinamool Congress leaders later trooped near the Speaker's podium and shouted slogans against the demonetisation move by the government.
Speaker Sumitra Mahajan urged the agitating members not to disturb the Question Hour as it was the right of the other members. But they did not relent.
As the din continued, Mahajan adjourned the House till 12.
