Do you want it to explode as well, or that it's just spawned?
You could add full damage to into to force explosion:
setDamage [1,TRUE];

  _boom="Bo_GBU12_LGB" createVehicle getPos whatever; _boom setDamage [1,true];
And in case you want to follow that traditional suggestion of initially creating the object on the "0,0,0" mark, and then move it to desired position immediately after:

  _boom = createVehicle ["Bo_GBU12_LGB",[0,0,0]]; _boom setPos (getPos whatever); _boom setDamage [1,true];  

My understanding or at least hope was Arma 4 was going to be Reforger but fleshed out to the degree Arma 4 was using the new engine and in particular the SP portion. It was the bridge to Arma 4 but I would expect it to be this plus all the technical things or most that happened in 3. So additions like sling roping etc, flight models and proper physics for things added over time but not necessarily a change in setting?   From there the modders can make it whatever anyone basically wants within reason.

Only real mod relevant here is Bacon Weather. The game looks amazing. We were up in the mountains yesterday and the cloud shadows moving across the landscape and the visuals were impressive.

arma 4 will be in cold war scenario (BI stated that all contents in reforger will are in ARMA 4).
So after update BI developer added AK74U and bayonet (but not the hand knife melee)
now the 6b4 vest and a aks 74 are mandatory (even the altyn helmet)
