By itself, each individual obstacle is rather ok... But a
combination of all, wo... thats forms the main reason why SOC is
one of the most feared activity in SAF... So given a choice, i
would say the most difficult of them all is the run down... cause
it suck your mental strength away... and cause you to wana shit...
and make your arms and legs goes soft... and makes you goes panting
like a dog... Thats why SOC is such a good measurement of stamina,
arm power, leg power, coordination and most importantly, mental
strength.
