your entire post was you hypothesizing about how Miranda's "could be" this or that. But we both know what it looks like. And that's the point. It looks like a skintight jumpsuit, as tight as spandex. And it looks ridiculous. You keep saying that it makes sense for the type of operations she'll be going on. I guess you missed that bit where she's following Shepard all over the galaxy into battle.
Secondly, I didn't stack any deck. I never stated anywhere in this thread that "most combat situations were in open areas". You're the one putting words in peoples mouths. Who said you get to choose where you fight? Do you see the future? The point is, being prepared for any situation, whether it be going into a CQC situation or trekking across the open landscape.
Well, mocking a post and dismissing it isn't beating it. And yes, Shepard is going across the galaxy, doing the kinds of operations that she's fit to do. A three person fire team (or the whole 12 person squad at full strength) isn't going into a battlefield. Now you're trying to tell me how I think as well. And I don't think it makes a valid premise for an argument, drawing a false conclusion based on your own appeal to ignorance.
And now you're trying to blame me for your statement: You're implying that there won't be an area of cover that won't work, and implying that it is the rule. You're making a very specific scenario and using it as singular justification to your point without drawing any kind of abductive conclusion (making connections that fit each other and the premise). And now, you're showing ignorance to military preparatory situation. That can be forgiven; for me, it can't be. Quite frankly, yes, I do get to choose where and when to fight. It's my job. I take all kinds of terrain models and geography into account when I'm planning an operation. It's something every military commander does. If I'm going to have to traverse a wide, open area, I don't want armor, I want armor (as in, a tank or APV) that has speed and power to get me across quickly and has survivability. That said, traversing an open area on foot is akin to tactical suicide unless you well and truly have no other option. Which, in the case of the game, you do.
As well, modularity is the key to being prepared for any situation, not packing everything you don't need. The old adage 'better to have it and not need it, rather than need it and not have it' falls under Murphy's Law real quick. Because if you're carrying that much excess baggage around with you at all times, you're gonna wear yourself out and reduce your own combat effectiveness. As I said, you're not trained to take things like this into consideration. So your ignorance is understandable. I'd wager Shepard took the necessary preparations for preparing and studying the battlefield prior to insertion, and made sure that everyone was acceptably ready for the mission parameters.
