IFF dilemas

Teaches: Mass Raid Prioritisation: Jets First, UAVs After, Unknowns Referred

The exercise

The brief the trainee reads

You hold a single battery defending the site, radar fixed on a 120-degree sector facing east. A mixed raid is inbound across that sector at the same time as scheduled civil traffic transits it. Magazine on the rails: 4 long-range, 5 medium-range, 4 short-range. Two rockets may be in the air at once — a third engagement cannot begin until one resolves. Identification doctrine for tonight: IFF interrogation is available out to 200 km on any held track. A Mode 3 reply and nothing else means civil traffic — engagement prohibited, and that includes emergency codes (7500/7600/7700); an aircraft in distress is still a civil aircraft. A Mode 1 reply means a military transponder; no own-force aircraft are airborne in your sector tonight, so a Mode 1 reply is not a friendly indication. A track that answers nothing gives you no reply to read and must be judged on its flight profile. Any track still showing Unknown is a question, not a permission — refer it and expect a classification back in about fifteen seconds; fire on nothing that is not Enemy. Fast closers consume the timeline. Interrogate early, classify, and take valid solutions as the system offers them.

What counts as success

Pass: all three jets destroyed before they reach the 20 km ring, at most one UAV leaking to the site, and no round fired at any track that answers Mode 3 or that was never classified Enemy. Interrogate before you classify. Engaging a civil track fails the run outright, whatever the hostile score. Holding fire while both rockets are committed is correct behaviour, not a failure to act; breaking or switching a good engagement is scored as an error even if it works.

At most 1 hostile may reach the defended area.

Shown as is what the console displays at first; really is the truth, which the trainee never sees. Where the two differ, the identification is the exercise.

What the trainee is issued

Stock is per round, and it is a training choice rather than a property of the system. The system's own maximum is set once in its profile and cannot be exceeded here.

long rangeof 4 the system holds
medium rangeof 6 the system holds
short rangeof 10 the system holds

13 rounds against 10 hostile tracks — 1.30 per hostile.

Enough to answer a miss, not enough to be careless. The system could hold 20 in all.

Nothing changed yet.

What is wrong with it?

Say it in your own words. Everything you have said before still applies, so a fix you already have does not come undone.

Test the system with live targets

The test flies its own built-in engagement rather than this one, so it checks the console and the figures rather than this exercise.
