In the M149A2 Water Trailer, what are the front link count, rear link count, and number of breakaways?

• A. 70, 85, 2
• B. 65, 95, 1
• C. 75, 90, 1
• D. 80, 92, 1

Answer: (C)

Safety chains and the breakaway system are there to keep a towed trailer under control if the connection to the tow vehicle fails. The front and rear link counts refer to how many chain links are used in the safety chains, and they’re set to match the hitch geometry and attachment points on the M149A2 so the chains stay taut but not snagging during turns or uneven terrain. The breakaway device provides automatic braking if the trailer becomes detached from the tow vehicle, enhancing stopping authority and preventing runaway trailers. The correct configuration follows the manufacturer’s towing setup for the M149A2: a front chain length that aligns with the hitch point, a rear chain length that reaches the trailer’s attachment points without excess slack, and a single breakaway mechanism to trigger emergency braking if separation occurs. This combination ensures proper control and safety under movement, while the other options would imply chain lengths that don’t fit the hitch geometry or more than one breakaway, which isn’t how the trailer is configured.
