Which kit's signal can be fired to an altitude of up to 650 ft?

• A. MK-124
• B. MK-79
• C. MK-53
• D. MK-45

Answer: (B)

Flares and signaling devices have specific altitude ratings that tell you how high their signal will travel, which affects how far away it can be seen. The MK-79 is designed to be fired up to about 650 feet, which matches the requirement in the question. It’s a compact, handheld signal flare intended to rise to a modest height quickly so observers at a distance can spot it. The other kits are used for different signaling purposes and aren’t described as reaching that 650-foot altitude, so they don’t fit the stated capability.
