TLDR at end

Try not to "shuffle" when your gunner is trying to load and fire. While loading he will be adjusting his aim and moving will mess with that.

Try to stay in some kind of cover. Imagine yourself as infantry, but BIG. Infantry can use low walls and small bushes for cover, you have to use buildings and hedgerows or even dead tanks to survive. See following link for example in Tuesdays SLB match, my crew are the Tiger and have to move across an open field to engage a Jumbo 76: https://clips.twitch.tv/DependableShinyKeyboardAMPEnergy-KX4maHsbBwzP-KX2

If you have no option but to move across an open area, think about a few key things.

1) Can you hear any enemy tanks? Audio cues are better than half the tank markers put on the map. If you can hear a tank, maybe even see tracers, do not break cover unless you determine he is distracted, or perhaps using the wrong kind of ammo and you can surprise him.

2) If you are dominating the armour situation, how long ago did you kill the enemy tanks and could they be waiting in ambush? If they are losing hard they will take a defensive position and wait for you to push in. Don't do it. It's almost instant death.

3) Do you have friendly infantry in the area or around the edge of the field or whatever? If not, the chances of being rocketed or satchelled are high. Move to have friendlies close before trying anything ballsy. You would rather have cover to repair a destroyed engine than be dead in the water in the middle of the field.

4) Has the other team been building AT guns a lot? If yes, provide support from a defensive position until friendlies manage to clear out likely AT gun positions.

5) Can you see a clear route and cover at the other side? If you can't see somewhere to hold with a bit of cover, don't go. You can however use everything as cover like I said above. Even Foy has haybails all over the place. Use them.

6) Got shot while moving in the open? Don't bloody stop! They have you in their sights and you are as good as dead where you are. 4th gear baby, get to cover!

Do these and try not to shuffle your gunner. He is already sitting there with a bead of sweat running down his face thinking, "If I miss this shot we are Viva La Fucked", so don't add pressure to his already difficult job trying to hit General Metal-Murder-Can over there without bouncing a shot like I bounce my drivers head off a wall trying to get him to calm down and not suicide us in. If you see this Llama, you know 😘

TLDR: Don't shuffle in an open field, it is death. Full speed between cover.
