think it would be nice to see a few more soldiers.
personally think we should see a soldier with an RPG here as a big threat, alert them and get shot by a rocket, would only fire one round then swap to a pistol or something but that one round would be enough to severely wound the player or if unlucky kill the guard ending the area. Having a heavy enemy would be enough to encurage stealth, while not requiring it. as all you would need to do is take out the RPG soldier first.
also I personally do not know why the soldiers are in the hanger, sure their is a copter in the hanger but no reason for the soldiers to be there. If it is their field command there would be more soldiers, but as it is it seems like a gaurd post that just happens to have a radio.
here is my full suggestion though doubt it would ever happen.
give the player an option of following the gaurds lead, or add taking on a moderate hecu force, for this I would suggest changing the room to look like a field command station, and adding more soldiers and gear in the room.
suggested lay out
near doors: 2 sand bag groups set to flank the room, neither is manned but both have .50 cals meaning if you go loud you are in a kill box
center: in teh center should be a entrenched area with the radio, some ammo boxes(infinite MP5+ grenade containers like in the hazard course mod). this area would have the commander and the dialog
elivator near where player enters: a .50 cal aimed into the room, un manned with some health near it (for the people wanting to go loud.
fuel truck area: several boxes looks like they where stacking supplies there.( little to no change)
copter: center it, and have 2 hecu grunts with out helmets, masks or armor working on it (pilots)
soldier numbers
near doors: 3, 2 on left side 1 on right.
center: 4, 2 commanders, 2 medics, one dead on a makeshift medical station.
copter: 2 pilots, one RPG soldier, said RPG soldier will only fire once before swapping to pistol. (only time a soldier is seen using an rpg before firing it)
room conditions: blow a hole in the celling, and make the door the soldiers leave through more secured, as well as have it actually open if you stealth, that way once you get through if you did not do combat you can loot the area for a good deal of ammo, health, and armor.
ways to take the room: 2
player can go with the coward of a guard and sneak around, leaving the group alive, or the player can get on the .50 cal and mow them down (or use their own guns). This makes it an optional hard fight, where the player can either sneak by or deal with the full force.
right now it just seems out of place, but that is more because of the numbers. Though I am betting it is more to make the guard look like a coward right now.
