Everyone has their own method of destruction..  Mine is NOT the cheapest. But most definitley the most through.   When im not tight for cash,  (which is like all the time,)  My method is Total annhilliation!
I do whatever necessary, Rocket launchers, heavy cannons, and Auto cannons, with HE and INCIDRENDARY ammunition.  This is good for several reasons..

#1  Plenty of light  (really useful on night missions!)
#2  Provides cover while ur cappin them!
#3 clears out ANYTHING that might POSSIBLY block ur next dudes line of fire!
#4  Very destructive. henceforth.  VERY EFFECTIVE

oh by the way.  once i get blaster launchers.  hehehe...   i take out a battle ship no problem A LANDED ONE even at night!!! 
                                         
                                          Part A
                    The Proper way to annhiliate an area

Well, not much to it..  if theres an orchard and u know theres resistance fire comming from the general area.. and you cant see that far..  HEY DONT RISK LOSING A SCOUT  JUST LEVEL THE PLACE!!!!   

    in my skyranger,  before i get an avenger.. 

I have 2 medikits on dudes with Heavy Plasmas
1 laser rifle man with 2 High Explosives and some alien grenades
2 Auto Cannoners, with 1 HE and 1 INCIDRENARY clips
2 Heavy Cannoners  with 1 HE and 1 INcidrendary a piece (and mebby 1 laser pistol for each)
and last but not least! 
1 Rocket Man with 2 small 1 Large and 1 Incidrendary rocket.

(all men carry 1 alien grenade, or regular grenade.



well.. thats about it for equipping.  now onto part B


                                          Part B
                              Startegy: Advance and Envelop


"Ok troops, ya got ur guns, lock and load. now its ur first mission..
Some of ya will not come back. but dont worry ur fighting for the Human race! your deaths shall be avenged!"

Well lets see.      STRATEGY 1:   THE SQUAD
Upon landing, have ur front men kill anything that can already be seen.
then deploy 2 men at a time, and get behind the legs, then deploy 2 at the end of ur ramp. (if necessary)

Now form a squad of a Auton cannon man and the 2 medics and a laser rifle demolitions man.   advance.  use your big boys in the back
for some SERIOUS cover,,  if ya cant get the bugger..   just get ur big boys in the back to aim,  and hope they hit the alien not ur guy,  (Always use aimed shots for long range, unless ur a rsk taking kinda person)

Then as your squad gets farther and farther away, get ur boys with the BIGGG guns to advance and follow.



                         STRATEGY 2:  1 SQUAD

I use this one sometimes, but not alot  (now since im farther in the game where everyone has armor, and HEAVY PLASMA they go in groups of 2 with my Blaster guys back at the avenger)


Well like i said, i do this with groups of 2 and everyone spreds out, or i stay in 1 large spread out skirmish line, and sweep the whole area.

This is very good depending on the situation.  Because all ur men can cover each other if 1 man misses the opprutunity.

Advanceing isnt too big a deal, just move forward, and save time units for Opp. fire




                     STRATEGY 3 : ALL FOR 1 AND 1 FOR ALL

OK, only use this if the baddies are few and far between.

this si simple, and good for buildings,  {so is strategy 2 (but use groups of 2)}
Ur on ur own here,  like the title says, all for 1 and 1 for all.   every man for himself.
