Ship components

[config]
name = f cr pnthr plasma mk2
guiname = F CR PNTHR Plasma MK2
hull = Federation Panther Cruiser hull

[modules]
0 = cruiser_armour V,
1 = cruiser plasma,
2 = cruiser heavy plasma,
3 = cruiser heavy plasma,
4 = cruiser_ecm shock,
5 = cruiser power III,
6 = cruiser heavy plasma,
7 = cruiser plasma,
8 = cruiser power III,
9 = cruiser_armour III,
10 = cruiser_engine V,
11 = cruiser crew II,
12 = cruiser shield II,
13 = cruiser shield fastrecharge,
14 = cruiser_ecm beam,

I was looking at the internals of one of my ships - this ship is no longer in my GSB directory and I don’t want to put it back. I wanted to build a copy. Except for one thing, what is the difference between these two modules?

4 = cruiser_ecm shock,
14 = cruiser_ecm beam,

I am assuming #4 is an EMP, what is the other one?

Your right number 4 is the EMP Cannon which knocks out the ship
The cruiser_ecm beam is the Guidance Scrambler Beam which knocks out the missile

Thank you, very much.
