Omani coastline is only 400kms away, no one needs to send an army there, this is not 1970s anymore, it can be blown up by stand off weapons, 50% of omani territory already falls within Babur's range if fired from the ground, surface vessels ie submarines will provide 100% territorial coverage, which means regardless of where the alleged Indian base hides, it will be bombed . Soon enough Babur cruise missile will be integrated on our naval assets both surface and submerged. Diplomatically we can simply get Riyadh to make them shut it down, again i highly doubt the credibility of this news.
For all who doesnt know, in an event of war UK will be supporting Oman. which is their agreements and that's why they have base in Masirah from where they operate fighters. They may have similar deal with United states as US military base is in Tumrait but I am not sure about it.
