A few army battalions from warring nations have met on an even battlefield. Each nation has one battalion present and all battalions have an equal number of soldiers. Every soldier is armed with one rifle and unlimited ammunition. Every soldier also has perfect shooting accuracy. And all armies follow the rules of engagement below.
Rules of Engagement
1. Each army battalion forms its own straight line queue
2. Each line is formed such that the head of each queue faces the head of the opposing army queue to its left (or when there are only two remaining armies, both queues face toward each other)
3. All queue heads maintain equal distance from their respective targets
4. There is a 1 second delay for each queue head to fire his weapon (time taken to lift weapon, aim, then fire)
5. If a queue head gets hit by any bullets during that 1 second delay (including at the exact moment the head is expected to shoot), he falls before he can fire his rifle. Otherwise, he shoots his rifle and immediately walks back to the end of his queue.
Note that the head will receive all bullets that reach his position during that round.
6. The next soldier in queue then takes his place as head at the start of the next round. If there is only one soldier remaining in a queue, he will stand in place and shoot his rifle every round until he falls or emerges victorious
7. An army is eliminated when all its soldiers have fallen. When an elimination occurs, the eliminator changes their target to the next army queue in sequence at the start of the next round.

8.A. If an elimination occurs during the round, then all remaining armies reposition themselves at the start of the next round and repeat the cycle from step 2. All bullets still in flight at the end of the round will miss all their targets when the repositioning occurs.

8.B If no elimination occurs in the round, start again from step...
