Well for 9 months of 2015 (reported on 10Q) we were at like 2.7 million, probably finished the year around 3.5 million.
In 2016 we can pretty much confirm due a very large project in Argentina that they did between 8-10 million.
No real visibility on what happened in 2017/2018 but with India running there had to be some sales.
It is funny , someone announces that crazy drone stock got a 650,000 dollar contract and people go nuts LOL We talking millions here!
Everything I post is my own opinion and people should always do their own research and due diligence on any company they are looking at
