Secondly, there is an imbalance between the strengths and weaknesses of the attacking

and defending sides
A single "blackout" mechanism that changes the lighting situation can give the defending side a significant advantage. Firstly, the attacking team is in motion and the torch will reveal their position, secondly, the defending team also has a night vision camera, which will allow them to switch between attacking and defending, but this will have a big impact on the overall game, whether they attack first or defend. So with limited lighting conditions, the best thing for the attacking side is to have a 5 man synchronised attack, as we see in film and television, with 5 man squads watching different areas.
