At approx 11:20-1130 Australian EDST at NWAF, one player A (myself) was killed climbing a tower with one shot instantly despite having full health, full ballistic helmet and heavy weight apparel.
We believe the inital shot would have been from the south east of the smoke stack
Subsequently, another player B (who was with player A) who remained in hiding not having moved behind a concrete berm was shot at once with a heavy rifle with expectation they would die but were protected by concrete. The unseen player (hacker) then repeatedly shot with heavy semi automatic fire directly at the concrete indicating they had no vision of the concrete but had vision of player B, possibly indicating vision hacks.
They then approached this area repeatedly shooting at the concrete until the player b eventually disconnected before they were killed.
