First let’s review the rules on placing them, (page 134 of the BRB) objectives are placed after terrain (though we normally have the terrain already set out on game day anyway) but before sides/deployment zones are decided.
· Roll off to see who places first marker, then alternate placing them.
· No objective marker can be placed with 6” of a battlefield edge, or within 12” of another objective marker.
· No objective marker can be placed on impassable terrain.
· No objective marker can be placed inside a building, though can be placed upon it. Should a building with an objective marker on it be removed, place the objective marker on the ground below the point it occupied. (Note that ruins are not buildings and so markers can be placed in them).
So, first thing we notice is no restriction on whether you can or can’t place them inside prospective deployment zones, as most missions you will already know what deployment option is going to be used (Dawn of War, Hammer & Anvil, or Vanguard Strike).
Now, when the tactical objective cards were first introduced I always tried to place them in the “no-man’s land” between the prospective deployment zones to give both players a chance of moving up to claim them.
However, in the competitive environment of tournament play in particular I find that more people (including myself now) tend to place them within the expected deployment zones and when deploying, put a unit within control range.
This doesn’t guarantee you vp’s though as there is still the roll off for choosing sides/zones and the randomness of actually drawing the right cards at the right time.
It can also depend on your choice of army style. If you’ve gone for the defensive gun line style you don’t want to moving too far so having markers in deployment markers makes sense, but if you’ve gone for a mobile strike force (elder jet bikes and marines in transports come to mind) you don’t then want to have them needing to sit back in your deployment zone so placing them further forward would be an advantage.
Another good reason for placing them further forward can be to utilise the “not within 12” rule, clever positioning of your markers can actually prevent your opponent placing his in a prospective deployment zone.
Using the standard set of tactical cards you get 3 chances to score points off each of the numbered markers so this could possibly score you 18 vp’s throughout the game , but again it’s dependant on drawing the right cards.
