What is a common feature of combat equipped jumpers in C-130 Hercules operations?

In C-130 Hercules operations, combat-equipped jumpers typically wear full combat gear to optimize their effectiveness upon landing. This includes additional equipment necessary for combat situations, such as weapons, ammunition, and survival tools that are essential for immediate engagement and mission success after parachuting. This full gear allows jumpers to be fully prepared to operate in potentially hostile environments as soon as they land.

The other options suggest characteristics that are not representative of the usual profile of soldiers conducting combat jumps. For instance, carrying only light gear would limit their combat capabilities, and while parachute certification is certainly important, it is expected in all jumpers regardless of their mission type. Specialized training for night jumps can be a requirement, but it's not a defining feature for all combat-equipped jumpers in general operations. Thus, being equipped with full combat gear is the common feature that prepares them for immediate action.
