A little suggestion on how to further enhance CovOps.
Heh heh 
Let’s make him a suicide-bomber:
He’ll have a special mujaheddin kind of button. This deadly device can be activated only after slow walking/standing still for at least 4 seconds (must be longer than it takes to detonate a satchel charge) – it means you can’t like run into a crowd of enemies and waste them all instantly. Moreover, when preparing to detonate, this must be visible to everyone, so that they have a choice: either to shoot you down before you are ready to press the red button, or to run away as fast as they can. The blast radius should be like the one of the satchel charge (or a bit broader) but it must be 100% deadly within these limits. This mujaheddin capacity can not be used to blow up doors, ramps, fences and stuff – only to kill enemy troops at close range.
Also, this can be made as a second option for using satchel charge – like CovOps Level 4 skill bonus (not unlike the Adrenaline-Self needle medic receives on Level 4 of his skills) – in this case it may be nice to award CovOps with a capability to instantly detonate satchel (and on his body).
Anyway – that’s just an idea – there can be many ways to prevent abuses.
