The Ferret is an anti-air missile battery that can easily shoot down most T1 and even some T2 aircraft.

Keep it cloaked to trick your enemy into thinking you don’t have anti-air.

It has more health than the Nettle—especially when popped down. Somewhat more reliable vs. bombers and gunships, it still should not be relied on as a primary defense due to its cost, though its ambush capability gives it unique value in some situations.

If hidden by a radar jammer, cloaked structures leave no radar 'ghost' to give them away once spotted.
