Dunno how is it, but I believe the healer and destroyer are some kind of classes, so how about something like:
PHP Code:
#define CLASS_HEALER 0
#define CLASS_DESTROYER 1
new gPlayerClass[ 33 ];
Than something like on some attack forward or what ever:
PHP Code:
if( gPlayerClass[ index ] == CLASS_DESTROYER && pev( index, pev_flags ) & IN_DUCK )
//Do thingys
