Sabotaged Communications appears to state that, for the round, the total orders issued by the opponent may not exceed what is written on the command card, minus one order. The opponent may not use coordinate to exceed this set limit. Is this a correct interpretation? Communications are supposed to be sabotaged, after all! 😉

it doesn't say total orders issued, it just says that they must issue one fewer orders than indicated on the command card, to a minimum of one. So that would mean you still could issue your normal-1 order(s) to lets say a B1 battle droid and it can still coordinate orders to other units.

Sabotated Communications only affects the orders issued by a command card. Any other orders (Entourage, HQ Uplink, etc.) are issued as normal.
