So I have talked about the
loss of Tech Adepts from Honour Guards in the past and
mention it from time to time when talking about Blood Angels. I however insist on keeping them in. I just use them as a Veteran armed with a Power Axe and carry on. It is a flavorful aspect of the Blood Angels and just looks impressive in an Honour Guard IMO. Alternatively, he can be used as just a Techmarine when I am not employing the Honour Guard.
Take a look at my latest efforts. He is simply a standard Space Marine Techmarine with an old Chaos Raptor Jump Pack. Since they did not appear too chaotic, with the correct paint job and paired with a suitable model, it really just gives a super appearance.
Oh and if you like the photography, please say so. My wife was kind enough to break out her camera and take these for me.
