Oh shit, sorry - it can hold a bool, just array initialization does not work. So, all you need for OP's question is

pawn Код:

new bool:ArmourUsed[MAX_PLAYERS char];

as all values will be false anyway.
If you need set all to true, you have to do it by hand:

pawn Код:

new bool:WhatBro[20 char]; 
main() 
{ 
    for(new i = 0; i < 20; i++) WhatBro{i} = true;
}
