You know, if you put 200,000 6 year olds on HGH now, in 12 years they will be big enough to carry M7 NGSWs no problem.
This, btw, makes the M7 the HEAVIEST standard issue infantry rifle in world history, beating the next runner up (the SUSAT-equipped Falkland's era FAL) by over three and a quarter pounds. The M7 is heavier than the fully equipped M4A1 it replaces by nearly 5.5 pounds.
