In IRON NEST Heavy Turret Simulator, each mission has its own Gold Medal requirements, and some of these conditions are not clearly explained in the game. In this guide, I explain the Gold Medal requirements I follow for each mission, including kill streaks, enemy kills, requisition limits, recon restrictions, accuracy, counter-battery time, and other mission-specific objectives.
Some medal requirements in IRON NEST Heavy Turret Simulator can be difficult to understand, so I use the following explanations to keep track of what each condition means.
Medal Clarification
Ally kills: I count every allied unit that dies during the mission, whether I caused the death myself or it happened because of another circumstance. For the best result, I aim for zero allied casualties.
Average accuracy: I am still not completely sure how this statistic works. Its apparent value range is 50 to 250, while normal mission shot accuracy only reaches 100%. It may instead measure how far a missed shot lands from the nearest target or enemy, with shorter distances giving a better result. I simply try to avoid missing whenever possible. STAR shells do not appear to affect this statistic because they do not impact the ground.
Consecutive kill shots: This is the number of killing shots I land in a row. If I miss a shot or fire a non-lethal shell, my current kill streak resets to 0.
Counter-battery time left: This is the remaining time displayed on the counter above the paper rolls at the back of the Iron Nest during missions with counter batteries. I do not want the timer to reach zero, and a higher amount of remaining time gives me a better medal result.
Enemies killed: This counts enemy casualties during the entire mission, whether I kill them myself or they die because of other circumstances. The Gold Medal requirement is often at or close to the maximum number of enemies in the mission, except in infinite missions.
Kills-per-shot ratio: I treat this as the number of enemies killed divided by the number of shots or impacts. I still need to confirm exactly how the game calculates this statistic.
Kills with a single shell: This requirement is currently unique to the Chill skirmish. I need at least one shot that kills the specified number of enemies with a single shell.
Recons requisitioned: I need to complete the mission without requisitioning aerial recon from scout planes. Spending requisition on a scout plane invalidates this medal. There is also an additional enemy-kill requirement that appears to be connected to the Enemies Killed medal in the same mission.
Requisition spent: I need to spend as little requisition as possible during the mission. I usually leave this medal until I have unlocked more shell types, especially the DRIL shell, which costs only 3 requisition.
Seconds until first shot: This measures how long I take to get out of bed, load a shell, and fire my first shot. Because the time limit is short, I start loading immediately and do my aiming while the loading animation is still running.
Triple kill time window: This appears to measure the time between the first shot impact and the third shot impact, although I have not fully verified it. My assumption is that each killing impact starts a new timer, which stops after two additional killing shots have landed, and the fastest completed timer is used for the medal.
Campaign Mission Gold Medal Requirements
Below, I list the Gold Medal requirements for each campaign mission. I include the medal name where it is known, what the requirement measures, and the value I need to reach.
Calibration Fire
Calibration Fire has only one medal requirement.

req_spent_30to100

30 or less
The 30-or-less requisition requirement can seem impossible when I first reach this mission because the cheaper shells have not been authorized yet. I can return later after unlocking them.

I have also found that the three-kill salvo Gold Medal may currently be awarded with a time of up to 45 seconds because of a typo in the requirement.

Unlike most requisition medals, this skirmish specifically requires me to spend more requisition rather than less.
