first week is alot of paper work ...alot of it and there is 1.5 mile run ,and jerry can carry over 150 meters. lifting 20kg ammo box etc. don't worry if u don't get under 10:30 bcz u will still pass as alot of our guys did even in week 14.
there r always good guys and some pricks everywhere so that goes for my section as well.
PT sessions r hard ,there is no doubt about it but remember u will feel the difference in ur later weeks , there is different types of PT seesions , muscular endurance and strength where u do circuit training, battle pt like assault courses and endurance runs like 3,4,5 mile steady run or fartlek runs .
