What is the M149 Water Trailer link count at the front and rear?

• A. 70 Front, 80 Rear
• B. 75 Front, 85 Rear
• C. 75 Front, 90 Rear
• D. 80 Front, 90 Rear

Answer: (C)

When balancing a sling-loaded load, you adjust how much weight is carried by each sling leg so the object stays level in flight. For the M149 water trailer, the center of gravity and the way the trailer’s mass is distributed means the rear needs a bit more sling length than the front. Using a longer rear sling (more links) helps counterbalance the trailer and keeps it level as it rides under the helicopter. So the front sling using 75 links and the rear sling using 90 links provides the proper balance: the rear is longer to offset the CG toward the back, helping maintain a stable, level attitude during lift and flight. If you swapped these numbers or used less length on the rear, the trailer could tilt and water could shift or spill, increasing risk to the mission. In practice, these counts come from standard load plans that consider the load’s weight distribution and the desired sling-angle limits to keep the operation safe.
