Figure out what the strategy of a paintball war like the Stalingrad event would be. If you were the company commander, how would you go about "winning"?
Maybe survey the battlefield to see where an advance would be easiest.
Allocate troops such that you concentrate forces in one spot to take ground, and hold ground in the other positions with as few troops as possible, so that the enemy is basically being inefficient with their forces (example: Imagine there are 10 areas and both sides have enough men to station 15 men at each area. You determine you can hold your ground with 10 men against 15, so you do that in 9 out of 10 areas, and then on the 10th area you take the extra (5 * 9 = 45) guys and add them to your 15 there to get 60 guys, and you crush the defense there. And then you just repeat that across the battlefield.
You would want to be able to set up communications with leaders at each area / battlefield so that you could quickly shift guys from one battle to an adjacent one if the enemy is starting to break through / take out friendlies on that battlefield.
Hyperventilation: Overbreathing either consciously or as a result of overexertion, artificially lowers carbon dioxide levels.
Oxygen-level drop: As the breath hold begins oxygen is metabolized and carbon dioxide levels increase. As the breath hold continues the body becomes starved of oxygen.
Unconsciousness: Under normal circumstances increased carbon dioxide would trigger a breath, but because CO2 levels were so low on submersion (due to hyperventilation), there is not enough to initiate a breath. The swimmer loses consciousness.
Drowning: Once the swimmer loses consciousness, the body reacts and forces a breath. That causes the lungs to fill with water and without an immediate rescue a drowning death is all but certain.
Never hyperventilate before swimming
Never ignore the urge to breathe
Never swim alone
Never play breath-holding games
No repetitive underwater laps. One lap, breathe.
Unlike regular drowning where there can be 6-8 minutes before brain damage and death, there are ONLY about 2 ½ minutes before BRAIN DAMAGE then DEATH with SWB because the brain has already been oxygen deprived coupled with warm water as in swimming pools, hastening brain death.
