CHAFF:  Radar-reflecting tinsel curtain propelled into the sky to confuse 
a homing missile's radar.

FLARE:  A pyrotechnic device to confuse heat-seeking missiles.

ABE:  A decoy.

JAM:  Jamming; incoming missile's radar emits certain parameters, and JAM 
scrambles the radar to confuse the incoming weapon.

IRJAM:  Infrared jamming; used against infrared missile seekers.

     IMPORTANT:  You must be in the manual mode of ECM in order to select 
countermeasure methods to deploy against hostile missile targets.

     NOTES:  You cannot activate any countermeasures when there is no 
active intercept. Countermeasures apply only to incoming hostile missiles.
If you attempt to deploy countermeasures against targets other than 
hostile missiles, nothing will happen (although you will waste your 
countermeasures).
