Infantry:
the m1a socom is a fantastic rifle and I love to use it.
the dmr is, in fact, useless.
the dragonov is similar to the dmr, but useful for sustained heavy aimed shots at close-medium range.
the aa12-he is a pos, he means high explosive but does less damage to vehicles than the incindeary.
the einfield is also, in fact, useless.
the melta definitely needs more ammo. u get 33 to reload, thats 11 shots. unless you can refill, this is useless for dealing with vehicles.
all bh with carapace armor are really lame actually. they just move too slow. tarantula is decent but I wouldnt buy the unit because its easily picked off by anyone with decent aim.
completely disagree with odellus on the bh elite (ak107), great anti-inf weapon.
completely disagree with threve on the pic sydneys. they do decent damage to vehicles, and some serious damage with heavy weapons upgrades. (mk2)
as for all the cheap units with rocket launchers that are not schlotskis, why bother, a free shotgun trooper's ats and the vulture are going to do better in ANY situation.
flame and chem backpack weapons are good, when u get them using a !wep. but if u buy the character, your too slow to do anything but remove barricades built by sappers.
the volt rifle is great, however if your using secondary fire, you have the same problem with ammo as the melta.
vehicles:
threve is wrong about titan 105mm, it moves much faster than titan rails.
there IS a decent Nod vehicle under 900, the t34 artillery. but yah, nothing has damage, mobility, or even armor/hp that can compete with the gdi selection. but tbh havent ever tried killing a pillbox with a spitfire apc. I would recommend changing reload time on the humv tow to something like the 10 shot amx.
Nod needs something comparable to the 400 churchill and the 800 centurion. the only real answer is the amphibious amx for 950 which has very little hp/armor, or the 1250 t54. and even if Nod wins that fight, nowhere near cost effective. bh light tanks might be an answer, but they need their cost reduced dramatically.
