Yes, they make a wide variety....of WWII German subjects.
Regarding the Abrams, DML/Dragon's offering is reportedly the worst of those available. A few months ago I read an exhaustive article comparing Abram kits from Tamiya, Italeri, Trumpeter, DML, and....Academy? I've lost the URL, so I can't point you to it, but I remember the DML/Dragon kit scored dead last with both poor fit and major accuracy problems. Tamiya's had the best fit and easiest assembly, but had some big inaccuracies, especially on the turret. Italeri came closest for accuracy (overdone non-skid surface notwithstanding).
All the companies produce both great kits and skunks, and in my (admittedly limited) experience, you just can't depend on the name alone. You can't trust newer kits over older, either. Look at Tamiya's "new" Desert Version M113A2.
My advice: Us the internet to find kit reviews. Places like http://www.missing-lynx.com/, www.ww2modelmaker.com, and http://www.perthmilitarymodelling.com/ review kits, and failing that go to www.google.com and search using the keyword review, along with the name of the subject or specific kit you're interested in. I've generally been able to find reviews of most kits, including obscure resin kits and conversions, with only a little effort.
