What I will need for this 1/2 of Turn 1 is for your team to post their Defensive Fire targets. This should include priorities such as something like this;
17/B8: 127, MMG - Fires at 17/D3 unless another target moves into the open within normal range.
You can be a little more detailed then above BUT please do not post an essay on possible fire options. Keep it as simple as possible.
IF an enemy unit moves adjacent you get what is called Final Protective Fire and I will handle all that on my end as there would be no need for you to tell me who should fire in those cases.
