In Vietnam the American military establishment consumed an estimated 50,000 rounds of ammunition for every enemy killed.
Back in the days before soldiers sprayed bullets about the field of battle promiscuously (i.e. The Civil War) it took about 60 rounds to "take out" one enemy soldier. The amount of ammunition used in WW2 resulted in 25,000 rounds per casualty. Usually, you go on a combat patrol with around 210 rounds; If you get into a firefight, your ammunition can deplete very quickly.
Yet what we saw in this movie, the frogman, call-sign Warhorse Once wasted his bullets to kill enemies like he had endless supplies of bullets from his logistic arsenal. He usually kept shooting with a salvo of 3 or 4 or even 5 bullets that resulted killing nobody, but when he shot just once, there's a kill. A veteran soldier, alone in the wildness, chased by swarm of enemies should and would never waste his bullets like what we saw in this moronic unrealistic firefights, but he just wasted his bullets so mindlessly generous. It's just made me shake my head non-stop sneering.
