Not that ECM would have helped against bullets in the same way that ECM won't help you against a ballistically launched, non-guided, SAM.
However, your comment ...
GR4's during GW2 ?

Due to the need, since 1991, to enforce the NFZs over Iraq the RAF already had some 25 aircraft and 1,000 personnel in the Gulf. During Operation TELIC a further 100 aircraft were deployed together with a further 7,000 personnel. This deployment included Tornado GR4s and Harrier GR7s in the offensive role, Tornado F3s for AD, VC10s and Tristars for AAR,Nimrods and Canberras in the recce role, E3-D Sentrys for AEWand control and Hercules and the new C17s for AT. Support Helicopters were also provided, 20 Chinooks and 7 Pumas.
The Tornado GR4s were fitted with the new Storm Shadow stand-off missile. Storm Shadow has a range of over 230 kilometres and can be used day or night in all weathers. It is designed to achieve exceptional precision against high value targets and minimise collateral damage.
Although the first bombs were dropped on 20 March 2003 the air campaign proper began on the 21 March. Precision attacks by both aircraft and cruise missiles were made against several hundred military targets in Iraq. These precision attacks continued for several weeks. As the land battle developed, an increasing number of CAS sorties were flown. Up to 700 sorties a day were flown against Iraqi ground forces and the RAF played a significant part in this effort. RAF aircraft flew 2,519 sorties, 1,353 of which were offensive strike, and released 919 weapons, approximately 85% of these were precisionguided. Operation TELIC also saw the first use of the Stormshadow stand-off precision air-to-ground missile.
