Shortcomings of the game engine and all, there was plenty of firepower and mobility for the Marine convoy to bypass the enemy resistance. Enemy fire at his point of the game scenario was frequent, but ineffective (as judged by the lack of effect on my vehicles and the visual cues offered by the game [amount of tracers coming out of the firing unit]). I also had the option to call a CAS mission (see screenshot above), but I refrained using it out of fear of getting some friendly fire incident like it happened in the real battle. I don't know if close air support missions can cause blue on blue in the Squad Battles game engine (only thing I've seen is friendly mortar fire falling on my troops). But better safe than sorry.
Other thing that was featured correctly in the game scenario is the enemy fire coming mostly from the west side of the convoy.
The scenario has already deviated from the real life battle because of that mobility kill, which happened some 2.3 km south of the Saddam Canal crossing.
Halfway through the scenario duration, things are going well (two objectives taken, almost reached the Saddam Canal, no casualties but a mobility kill suffered). But the battle is getting more intense.
To be continued ...
