They said information has been circulated throughout all formations to ensure that the Manipur Police Commando uniform, black in colour, is not misused and they have been instructed to intensify the vigil.
Often during the day or night, there is intermittent firing where these groups are taking shots at these quadcopters, available freely in the market, the officials said.
"Next challenge for us is to win elections, neither individuals nor statements matter, those are bygones," he said.
The development came two days after Manipur Chief Minister N Biren Singh said that a decision has been taken to provide security to the farmers who will start the cropping season.
The officials said that the recently developed SH-15, a 155 mm truck-mounted howitzer gun, has also been spotted at some places along the Line of Control after it was displayed on Pakistan Day last year.
A basic outline and roadmap for Opposition unity are likely to be deliberated upon with the contentious issue of seat sharing and leadership questions to be avoided for now.
Sources said the opposition parties would look to avoid the prickly leadership question as of now and emphasise on building a common ground.
Sibal, a prominent Opposition voice and a former Congress leader, also said that instead of a common minimum programme, the Opposition parties should talk about a 'new vision for India'.
As part of the deradicalisation strategy, the army, with the cooperation of the Union Territory administration, has undertaken a series of initiatives.

The ongoing crackdown on Khalistan supporters has brought to light a questionable delay in revoking arms licences granted to the armed guards of radical preacher Amritpal Singh in Jammu and Kashmir, officials said.
The Facebook page amassed a huge following, causing confusion among people, who assumed that Amritpal had taken over the organisation created by Deep Sidhu.
The Income Tax notice was recovered from the house of Baljeet Kaur at Shahabad in Kurukshetra in Haryana where Papalpreet and Amritpal had taken shelter on March 19 and 20 before fleeing from there.
The radical preacher's brazen activities evinced his methodical efforts to undermine the fabric of society, they claimed and added that he during his speeches and sermons alleged that the government was leaving no stone unturned in its quest to disarm Sikhs by revoking their weapons licences.
This was a major miscalculation on the part of the state police, the officials said while piecing together the turn of events since February 23 when Singh, a Khalistan advocate, had stormed a police station in Ajnala of Amritsar district and secured the release of his aide Lovepreet Singh Toofan.
The surprising part was that seven of his personal security officers were youngsters, who had joined his drug de-addiction centre for rehabilitation, the officials said, adding that during their stay there for treatment they had been imparted training.
Officials said Papalpreet Singh is considered one of Amritpal Singh's mentors who had been advising him on various issues.
Ramesh, however, said it was too early to talk about all this right now as the Congress' first priority was the upcoming elections in Karnataka and the string of state polls this year.
