Grenades are long distance knives, apparently. The sniper section will fail you automatically if you get too far ahead. Also Sarge & Sweets will take longer. Shooting the first two groups works though. Grabbing the LMG is unnecessary, but adds a little security for the river section. Not having to reload if you miss the nade is nice. Forgot to hit Top of hill split at correct time. Grabbing rockets from supply box to shoot car saves time. There are a few chokes here and there, can be optimized.
