Ghost Recon Breakpoint Echelon Rank 15 Challenge Kill 10 Enemies In 40 Seconds In The Channels

I Chose this place as its between 2 bases so get extra enemies to shoot at , there&probably a better place to do this challenge but it worked out for me so cant complain , even though it must of been close to timing out I think. Location : Channels : Tower Between Red Shark Outpost & Navy fuelling Station
