Four & Five.

This is coolbert:

MADIS [anti-drone system] as per the previous blog entry designed to engage and destroy enemy drones of the Group 4 and Group 5 category.

From the wiki those groups defined.

1. Group 4.  Type specimens to include: MQ-8B Fire Scout, MQ-1A/B Predator, MQ-1C Gray Eagle.

MQ-8B Fire Scout. Personnel giving you some sense of scale.

2. Group 5. Type specimens to include: MQ-9 Reaper, RQ-4 Global Hawk, MQ-4C Triton.

RQ-4 Global Hawk. Again personnel giving you some sense of scale.

Group four and five sized drones able to carry considerable munitions, "bang-stuff" with lethal consequences if used in the manner of a kamikaze!

Smaller sized drones MADIS not able to counter? More on this to follow.
