A dead VG is worth 3 exp right? If I kill 3 and force a retreat. Later they come back And I kill 3 more and make them retreat. I think I have gained 18 exp. IF I KIA the whole squad I get 15 exp and have to face grenadiers next time. Cons are better at killing VGs then Grens.
Or the more likely situation:
You kill 3 VG and they run. They come back reinforced and with another conscript squad or worse, a MG. You have 2 conscript squads (lets say you got another one to back you up since in this situation you seem to favor conscripts). Suddenly you are probably going to lose. In fact from the last engagement you lost 3 or even 4 conscripts and deciding that you probably were okay atm you wouldn't need to retreat for reinforce. Now you must retreat
.
You kill 3 VG and they run. They come back reinforced but this time with a VG squad and a Gren squad. You are in green cover you you are likr "okay I got this". The battle wears on and your conscripts are weak and you'll probably have to fall back soon. Suddenly you notice the volks are getting closer and closer. You think to yourself "Oh well, he is taking more damage anyhow". Suddenly the volks' MP40 upgrade is done and they charge you, decimating your units. You retreat.
Either way the comp isn't just going to wait for you to kill it's units and then get a new one (unless it's honestly out of popcap, but thats gameplay, especially late game)
