Yes, I may also remove or change HQ for sub-units during the campaign. For example,

As German, I start with 3 sections of 8cm mortars (B0-B2). Sometime after Eastern Front, I will pass command of 1 section (B2) to 1 of the infantry companies (G0), and upgrade the remaining 2 sections to 12cm mortars.

Starting core
B0-B2- 3 sections of 8cm mortars
G0- Company Commander
G1- AT Rifle Section

After Eastern Front
B0-B1- 2 sections of 12cm mortars
G0- Company Commander
G1- 1 section of 8cm mortars
G2- AT Rifle section

Conversely, I will sometimes add 1 core unit for the purposes of changing their sub-unit's HQ, and then deleting the core unit after the battle. Similar to the case above. This is what happens

Starting core
K0- Company Commander
K1- AT Rifle Section
O0- Company Commander
O1- AT Rifle Section

After Eastern Front
Added T0-T2- 3 sections of 8cm mortars

K0- Company Commander
K1- 1 sect of 8cm mortars
K2- AT Rifle Section
O0- Company Commander
O1- 1 sect of 8cm mortars
O2- AT Rifle Section
T0- 1 section of 8cm mortars (to be deleted at end of battle)
