IMHO the MSTM is not very useful against ground targets, mostly because the XFA-27 is an air-to-air Multirole, just like many others. For example, HERE if you upgrade your Sp.W. to lv.4 you can begin using the weapon against XSAM.

I can tell you that my friend Vik, once he unlocked the MSTM, was to quickly upgrade it to lv.5, because of THIS : note how strong the MSTM weapon is here, but also beware how "useless" the Std. missiles have become.
