After reading the new article for the Rebel Commandos, I went and re-read the rules for Arm X and Detonate X. In the current rules, if there is a Proton Charge Saboteur on both sides, then I see nothing preventing a player to detonate a charge that was just placed by the opponent. The rules say:

"After a unit controlled by any player performs an action, each unit that has a weapon with the detonate x: charge type keyword may detonate x friendly charge tokens of the specified type. See “Detonate” on page 26."

"If, after a unit performs an action, both players have units with the detonate x: charge type keyword that could detonate charge tokens, the player that does not control the unit that just performed an action may use their unit’s detonate x: charge type keyword first."

The Arm X is an action, so this scenario is possible:
-Blue player Proton Charge Saboteur uses his Arm 1 action to place the charge.
-As a unit from the blue player just performed an action which is the trigger, the red player Proton Charge Saboteur chooses to use the Detonate 1 abbility to detonate 1 charge, and chooses the one the blue player just placed.

Am I missing something or this is a legal move actually?

"After a unit controlled by any player performs an action, each unit that has a weapon with the detonate x: charge type keyword may detonate x friendly charge tokens of the specified type. See “Detonate” on page 26."

Of course, I had the answer under my nose all the time.

Thanks

Although...a commando could go on a suicide charge, if you thought the payoff would be good enough. Run into a cluster of enemy troops, drop the charge then immediately detonate it. Lose one unit for potentially many ?

Well, you don't actually have to lose the unit. The unit leader can walk up, leave the Joe in a position where the charge doesn't have LoS to them, place and detonate the charge.

Because charges are a ranged attack and the Joe is not in LoS, they can't be a casualty. If the leader does die, they'll just replace the Joe and you'll still have a saboteur.

Rebel terrorist tactics know no limit to their callous disregard for life!

Says under arm x when you place the token you need line of sight to where it is been placed .

It needs LOS to the leader, not to every mini. They’re suggesting leaving the non-leader minis out of LOS so they can’t suffer wounds.
