I know that under FAS, some Regular units will have TA personnel as part of the structure (and visa versa). In fact it may already be the case already. Some examples from FAS: a regular bty in the TA STA artillery regiment a TA sqn as part of 33 Engr Regt (EOD) a TA topographic sqn as part of 42 Engr Regt (Geo) TA platoons for RMP companys I forsee one problem with the fact that 1 or 2 TA infantry battalions will be part of each Regiment and will work only with them - the rest of the regiment (Regulars) could be based (semi-permanently under FAS) at the other end of the country or in Germany. That is unless for example, the former Chesires (regular) are based in the general area of Chesire. This is a simified example. Could the TA be better organised & trained by the more wide spread use of this? For example, each regular army Infantry Battalion & Artillery Regiment could have a formed TA company/battery to augment it to warfighting strength.
