Anyone else for amusement value done an all grenade squad? Smokes, Plasmas, Frags, Infernos, flashbangs...
Grab your highest TU soldiers, load 'em up with grenades, and clear rooms without ever firing a shot... though lots of smoke. XD
These squads are rediculously nasty, and tend to be quite effective. I've even used them on Very Hard to good effect unless the board is a sniper heaven (IE: Dam). The only problem... Lots and lots of dead civvies. XD Oops! Run you fools!
